7bef4c48d6 [dsymutil] Rename a variable to appease some bots.
Anyway having the type and the name of the member being the same
thing wasn't the wisest of the choices.

dfbf8971ca [dsymutil] Have the YAML deserialization rewrite the object address of symbols.
The main use of the YAML debug map format is for testing inside LLVM. If we have IR
files in the tests used to generate object files, then we obviously don't know the
addresses of the symbols inside the object files beforehand.

This change lets the YAML import lookup the addresses in the object files and rewrite
them. This will allow to have test that really don't need any binary input.

527bb619d1 [dsymutil] Out-line the YAML serialization code. NFC
It will get a bit bigger in an upcoming commit. No need to have all
of that in the header.

Also move parseYAMLDebugMap() to the same place as the serialization
code. This way it will be able to share a private Context object with
it.

786b471cc6 [dsymutil] Use YAMLIO to dump debug map.
Doing so will allow us to also accept a YAML debug map in input as using
YAMLIO gives us the parsing for free. Being able to have textual debug
maps will in turn allow much more control over the tests, because 1/
no need to check-in a binary containing the debug map and 2/ it will allow
to use the same objects/IR files with made-up debug-maps to test
different scenari.

e7a356409d [dsymutil] Add function size to the debug map.
The debug map embedded by ld64 in binaries conatins function sizes.
These sizes are less precise than the ones given by the debug information
(byte granularity vs linker atom granularity), but they might cover code
that is referenced in the line table but not in the DIE tree (that might
very well be a compiler bug that I need to investigate later).
Anyway, extracting that information is necessary to be able to mimic
dsymutil's behavior exactly.

e9483b84f0 [dsymutil] Add DebugMapObject::lookupObjectAddress()
It turns out the debug map will be interogated both by name and
by object file address. Add the latter capability.

8732027cd8 [dsymutil] Add the detected target triple to the debug map.
It will be needed to instantiate the Target object that we will
use to create all the MC objects for the dwarf emission.

1b279144ec [cleanup] Re-sort all the #include lines in LLVM using
utils/sort_includes.py.

I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

31e081ed96 Initial dsymutil tool commit.
The goal of this tool is to replicate Darwin's dsymutil functionality
based on LLVM. dsymutil is a DWARF linker. Darwin's linker (ld64) does
not link the debug information, it leaves it in the object files in
relocatable form, but embbeds a `debug map` into the executable that
describes where to find the debug information and how to relocate it.
When releasing/archiving a binary, dsymutil is called to link all the DWARF
information into a `dsym bundle` that can distributed/stored along with
the binary.

With this commit, the LLVM based dsymutil is just able to parse the STABS
debug maps embedded by ld64 in linked binaries (and not all of them, for
example archives aren't supported yet).

Note that the tool directory is called dsymutil, but the executable is
currently called llvm-dsymutil. This discrepancy will disappear once the
tool will be feature complete. At this point the executable will be renamed
to dsymutil, but until then you do not want it to override the system one.
