This is to reflect the evolving nature of the tool as being
useful for more than just dumping PDBs, as it can do many other
things.

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).

1. Added some asserts to make sure concrete symbol types don't
get constructed with RawSymbols that have an incompatible
SymTag enum value.
2. Added new forwarding macros that auto-define an Id/Sym method
pair whenever there is a method that returns a SymIndexId.
Previously we would just provide one method that returned only
the SymIndexId and it was up to the caller to use the Session
object to get a pointer to the symbol. Now we automatically
get both the method that returns the Id, as well as a method
that returns the pointer directly with just one macro.
3. Added some methods for dumping straight to stdout that can
be used from inside the debugger for diagnostics during a
debug session.
4. Added a clone() method and a cast<T>() method to PDBSymbol
that can shorten some usage patterns.

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.

We were starting to get some name clashes between llvm-pdbdump
and the common CodeView framework, so I took this opportunity
to rename a bunch of files to more accurately describe their
usage. This also helps in llvm-pdbdump to distinguish
between different files and whether they are used for pretty
dump mode or raw dump mode.
