The unobufscation support for BCSymbolMaps was the last piece of code
that hasn't been upstreamed yet. This patch contains a reworked version
of the existing code and relevant tests.

Now that almost all functionality of Apple's dsymutil has been
upstreamed, the open source variant can be used as a drop in
replacement. Hence we feel it's no longer necessary to have the llvm
prefix.

The invocation without -no-output would try to lipo the different debug
objects together. This wouldn't work on platforms that don't provide
that utility.

Threading was disabled in r317263 because it broke a test in combination
with `-DLLVM_ENABLE_THREADS=OFF`. This was because a ThreadPool warning
was piped to llvm-dwarfdump which was expecting to read an object from
stdin.
This patch re-enables threading and fixes the offending test.
Unfortunately this required more than just moving the ThreadPool out of
the for loop because of the TempFile refactoring that took place in the
meantime.

This patch adds timestamp verification for swiftmodule files.
- A new flag is provided to allows us to continue testing of the code
for embedding the__swift_ast. (git doesn't maintain timestamps)
- Adds a new test for fat (arm) binaries.

As discussed on llvm-dev in
http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html
this changes the command line interface of llvm-dwarfdump to match the
one used by the dwarfdump utility shipping on macOS. In addition to
being shorter to type this format also has the advantage of allowing
more than one section to be specified at the same time.
In a nutshell, with this change
$ llvm-dwarfdump --debug-dump=info
$ llvm-dwarfdump --debug-dump=apple-objc
becomes
$ dwarfdump --debug-info --apple-objc

Summary:
Based on Fred's patch here: https://reviews.llvm.org/D6771
I can't seem to commandeer the old review, so I'm creating a new one.
With that change the locations exrpessions are pretty printed inline in the
DIE tree. The output looks like this for debug_loc entries:
DW_AT_location [DW_FORM_data4] (0x00000000
0x0000000000000001 - 0x000000000000000b: DW_OP_consts +3
0x000000000000000b - 0x0000000000000012: DW_OP_consts +7
0x0000000000000012 - 0x000000000000001b: DW_OP_reg0 RAX, DW_OP_piece 0x4
0x000000000000001b - 0x0000000000000024: DW_OP_breg5 RDI+0)
And like this for debug_loc.dwo entries:
DW_AT_location [DW_FORM_sec_offset] (0x00000000
Addr idx 2 (w/ length 190): DW_OP_consts +0, DW_OP_stack_value
Addr idx 3 (w/ length 23): DW_OP_reg0 RAX, DW_OP_piece 0x4)
Simple locations without ranges are printed inline:
DW_AT_location [DW_FORM_block1] (DW_OP_reg4 RSI, DW_OP_piece 0x4, DW_OP_bit_piece 0x20 0x0)
The debug_loc(.dwo) dumping in changed accordingly to factor the code.

r267249 removed the dual ARM/Thumb interface from MachOObjectFile,
simplifying llvm-dsymutil's code. This unfortunately also regressed
llvm-dsymutil's ability to select thumb slices, because the simplified
code was also dealing with the discrepency between the slice arch
(eg. armv7m) and the triple arch name (eg. thumbv7m).

Only one consumer (llvm-objdump) actually cared about the fact that there were
two triples. Others were actively working around the fact that the Triple
returned by getArch might have been invalid. As for llvm-objdump, it needs to
be acutely aware of both Triples anyway, so being generic in the exposed API is
no benefit.
Also rename the version of getArch returning a Triple. Users were having to
pass an unwanted nullptr to disambiguate the two, which was nasty.
The only functional change here is that armv7m and armv7em object files no
longer crash llvm-objdump.

Although it seems like clang will never emit scattered relocations in
the debug information (at least I couldn't find a way), we have too
support them for the benefit of other compilers.
As clang doesn't generate them, the included testcase was produced
from hacked up assembly.

The value of an inlined subprogram low_pc attribute should not
get relocated, but it can happen that it matches the enclosing
function's start address and thus gets the generic treatment.
Special case it to avoid applying the PC offset twice.

There was an issue in the test setup because the test requires an arch that
wasn't filtered by the lit.local.cfg, but given the set of bots that failed,
I'm not confident this is the (only) issue. So this commit also adds more
output to the test to help me track down the failure if it happens again.
Original commit message:
[dsymutil] Rewrite thumb triple names in user visible messages.
We autodetect triples from the input file(s) while reading the mach-o debug map.
As we need to create a Target from those triples, we always chose the thumb
variant (because the arm variant might not be 'instantiable' eg armv7m). The
user visible architecture names should still be 'arm' and not 'thumb' variants
though.

This reverts commit r245960.
Multiple bots are failing on the new test. It seemd like llvm-dsymutil exits with an error. Investigating.

dsymutil should by default generate dSYM bundles which are filesystem
hierarchies containing the debug info and an additional Info.plist.
Currently llvm-dsymutil emits raw binaries containing the debug info.
This is what we call the 'flat mode'. Add a -f/-flat option that is
supposed to enable that flat mode, but don't wire it for now, only
pass it to the tests that will need it to stay functional once we
do bundle generation by default.
This basically makes this commit NFC and removes the noise from the
actual commit that adds support for bundle generation.

This patch allows llvm-dsymutil to read universal (aka fat) macho object
files and archives. The patch touches nearly everything in the BinaryHolder,
but it is fairly mechinical: the methods that returned MemoryBufferRefs or
ObjectFiles now return a vector of those, and the high-level access function
takes a triple argument to select the architecture.
There is no support yet for handling fat executables and thus no support for
writing fat object files.
