llvm-pdbdump was renamed to llvm-pdbutil long ago. This updates the test
to be where you'd expect them to be.

Running "llvm-pdbutil dump -all" on linux (using the native PDB reader),
over a few PDBs pulled from the Microsoft public symbol store uncovered
a few small issues:
- stripped PDBs might not have the strings stream (/names)
- stripped PDBs might not have the "module info" stream

These work a little differently because they are actually in
the globals stream and are treated as symbol records, even though
DIA presents them as types. So this also adds the necessary
infrastructure to cache records that live somewhere other than
the TPI stream as well.

This command can dump the binary contents of a stream to a file.
This is useful when you want to do side-by-side comparisons of
a specific stream from two PDBs to examine the differences between
them. You can export both of them to a file, then open them up
side by side in a hex editor (for example), so as to eliminate any
differences that might arise from the contents being on different
blocks in the PDB.
In subsequent patches I plan to improve the "explain" subcommand
so that you can explain the contents of a binary file that isn't
necessarily a full PDB, but one of these dumped streams, by telling
the subcommand how to interpret the contents.

This will show more detail when using `llvm-pdbutil explain` on an
offset in the DBI or PDB streams. Specifically, it will dig into
individual header fields and substreams to give a more precise
description of what the byte represents.

When we determine that a field belongs to an MSF super block or
the free page map, we wouldn't print any additional information.
With this patch, we now print the value of the field (for super
block fields) or the allocation status of the specified byte (in
the case of offsets in the FPM).

We were trying to dig into the super block fields and print a
description of the field at the specified offset, but we were
printing the wrong field due to an off-by-one-field-error.

When investigating various things, we often have a file offset
and what to know what's in the PDB at that address. For example
we may be doing a binary comparison of two LLD-generated PDBs
to look for sources of non-determinism, or we may wish to compare
an LLD-generated PDB with a Microsoft generated PDB for sources
of byte-for-byte incompatibility. In these cases, we can do a
binary diff of the two files, and once we find a mismatched byte
we can use explain to figure out what that byte is, immediately
honining in on the problem.
This patch implements this by trying to narrow the meaning of
a particular file offset down as much as possible.

This test was originally disabled because it was failing on a bot.
It turns out I had run dos2unix on the file, and that removed a
necessary byte from the file. I'm just recomitting the proper
file and updating the test to test a little bit more now.

Injected sources are basically a way to add actual source file content
to your PDB. Presumably you could use this for shipping your source code
with your debug information, but in practice I can only find this being
used for embedding natvis files inside of PDBs.
In order to effectively test LLVM's natvis file injection, we need a way
to dump the injected sources of a PDB in a way that is authoritative
(i.e. based on Microsoft's understanding of the PDB format, and not
LLVM's). To this end, I've added support for dumping injected sources
via DIA. I made a PDB file that used the /natvis option to generate a
test case.

Summary:
- Fix a bug in PrettyBuiltinDumper that returns "void" as the name for
an unspecified builtin type. Since the unspecified param of a variadic
function is considered a builtin of unspecified type in PDBs, we set
"..." for its name.
- Provide a method to determine if a PDBSymbolFunc is variadic in
PrettyFunctionDumper since PDBSymbolFunc::getArgument() doesn't return the
last unspecified-type param.
- Add a pretty-func-dumper.test to test pretty dumping of variadic
functions.

We had a lot of one-off tests for this type and that type,
or "every type that happens to be generated by this program
I built". Eventually I got a bug report filed where we were
crashing on a type that was not covered by any of these tests.
So this test carefully constructs a minimal C++ program that
will cause every type we support to be emitted. This ensures
full coverage for type records.

Previously we had the -type-index option which would dump the record of
a single, but we had no way to follow the dependency graph backwards and
also dump all dependent types.
Having this option makes test-writing better, because we can limit the
test to only those records that are of importance for the thing we're
trying to test, which allows us to use things like CHECK-NEXT to reduce
fragility.

After some internal discussions, we agreed that the raw output style had
outlived its usefulness. It was originally created before we had even
thought of dumping to YAML, and it was intended to give us some insight
into the internals of a PDB file. Now we have YAML mode which does
almost exactly this but is more powerful in that it can round-trip back
to a PDB, which the raw mode could not do. So the raw mode had become
purely a maintenance burden.
One option was to just delete it. However, its original goal was to be
as readable as possible while staying close to the "metal" - i.e.
presenting the output in a way that maps directly to the underlying file
format. We don't actually need that last requirement anymore since it's
covered by the yaml mode, so we could repurpose "raw" mode to actually
just be as readable as possible.
This patch implements about 80% of the functionality previously in raw
mode, but in a completely different style that is more akin to what
cvdump outputs. Records are very compressed, often times appearing on
just one line. One nice thing about this is that it makes full record
matching easier, because you can grep for indices, names, and leaf types
on a single line often.
See the tests for some examples of what the new output looks like.
Note that this patch actually regresses the functionality of raw mode in
a few areas, but only because the patch was already unreasonably large
and going 100% would have been even worse. Specifically, this patch is
missing:
The ability to dump module debug subsections (checksums, lines, etc)
The ability to dump section headers
Aside from that everything is here. While goign through the tests fixing
them all up, I found many duplicate tests. They've been deleted. In
subsequent patches I will go through and re-add the missing
functionality.

When dumping raw data from a stream, you might know the offset
of a certain record you're interested in, as well as how long
that record is. Previously, you had to dump the entire stream
and wade through the bytes to find the interesting record.
This patch allows you to specify an offset and length on the
command line, and it will only dump the requested range.

The *real* difference between these two was that
a) The "graphical" dumper could recurse, while the text one could
not.
b) The "text" dumper could display nested types and functions,
while the graphical one could not.
Merge these two so that there is only one dumper that can recurse
arbitrarily deep and optionally display nested types or not.

This reworks the way virtual bases are handled, and also the way
padding is detected across multiple levels of aggregates, producing
a much more accurate result.

In a followup patch I intend to introduce an additional dumping
mode which dumps a graphical representation of a class's layout.
In preparation for this, the text-based layout printer needs to
be split out from the graphical layout printer, and both need
to be able to use the same code for printing the intro and outro
of a class's definition (e.g. base class list, etc).
This patch does so, and in the process introduces a skeleton
definition for the graphical printer, while currently making
the graphical printer just print nothing.

Previously the dumping of class definitions was very primitive,
and it made it hard to do more than the most trivial of output
formats when dumping. As such, we would only dump one line for
each field, and then dump non-layout items like nested types
and enums.
With this patch, we do a complete analysis of the object
hierarchy including aggregate types, bases, virtual bases,
vftable analysis, etc. The only immediately visible effects
of this are that a) we can now dump a line for the vfptr where
before we would treat that as padding, and b) we now don't
treat virtual bases that come at the end of a class as padding
since we have a more detailed analysis of the class's storage
usage.
In subsequent patches, we should be able to use this analysis
to display a complete graphical view of a class's layout including
recursing arbitrarily deep into an object's base class / aggregate
member hierarchy.

When dumping classes, show where padding occurs, and at the end of the
class print statistics about how many bytes total of padding exist in a
class.
Since PDB doesn't specifically contain information about padding, we have
to mimic this by sort of reversing a small portion of the record layout
algorithm (e.g. looking at offsets and sizes and trying to determine
whether something is part of the same field or a new field).

Previously when dumping class definitions, there were only
two modes - on or off. But it's useful to sometimes get a
little more fine-grained. For example, you might only want
to see the record layout (for example to look for extraneous
padding). This patch adds a third mode, layout mode, which
does exactly that. Only this-relative data members are
displayed in this mode.

Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings.
There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.

PDB files have a lot of noise in them, with hundreds (or thousands)
of symbols from system libraries and compiler generated types. If
you're only looking for a specific type, this can be problematic.
This CL allows you to display *only* types, variables, or compilands
matching a particular pattern. These filters can even be combined
with exclude filters. Include-only filters are given priority, so
that first the set of items to display is limited only to those that
match the include filters, and then the set of exclude filters is
applied to those. If there are no include filters specified, then
it means "display everything".

This patch adds the --load-address command line option to
llvm-pdbdump, which dumps all addresses assuming the module has
loaded at the specified address.

This will now display enum definitions both at the global
scope as well as nested inside of classes. Additionally,
it will no longer display enums at the global scope if the
enum is nested. Instead, it will omit the definition of
the enum globally and instead emit it in the corresponding
class definition.

A short list of some of the improvements:
1) Now supports -all command line argument, which implies many
other command line arguments to simplify usage.
2) Now supports -no-compiler-generated command line argument to
exclude compiler generated types.
3) Prints base class list.
4) -class-definitions implies -types.
5) Proper display of bitfields.
6) Can now distinguish between struct/class/interface/union.
And a few other minor tweaks.
