Zachary Turner fced530650 Revert "Resubmit "Support embedding natvis files in PDBs.""
This is still failing on a different bot this time due to some
issue related to hashing absolute paths.  Reverting until I can
figure it out.

Zachary Turner 132d7a134f Resubmit "Support embedding natvis files in PDBs."
The issue causing this to fail in certain configurations
should be fixed.

It was due to the fact that DIA apparently expects there to be
a null string at ID 1 in the string table.  I'm not sure why this
is important but it seems to make a difference, so set it.

Hans Wennborg ceecf3bbda Revert r327964 "lit: Make config.llvm_libxml2_enabled an int, not a string"
It seems @LLVM_LIBXML2_ENABLED@ doesn't always get set to 0 when not available,
but to nothing, which broke parsing of lit.site.cfg.py.

Hans Wennborg c6b5f3833e lit: Make config.llvm_libxml2_enabled an int, not a string
@LLVM_LIBXML2_ENABLED@ will be replaced with 0 or 1. Putting quotes
around that is unnecessary and just makes it harder to use the value.
This matches what have_zlib does below.

This also puts the flag together with the feature-related ones instead
of the path-related flags.

This is causing a test failure on a certain bot, so I'm removing
this temporarily until we can figure out the source of the error.

Zachary Turner de53aaf132 Support embedding natvis files in PDBs.
Natvis is a debug language supported by Visual Studio for
specifying custom visualizers.  The /NATVIS option is an
undocumented link.exe flag which will take a .natvis file
and "inject" it into the PDB.  This way, you can ship the
debug visualizers for a program along with the PDB, which
is very useful for postmortem debugging.

This is implemented by adding a new "named stream" to the
PDB with a special name of /src/files/<natvis file name>
and simply copying the contents of the xml into this file.

Additionally, we need to emit a single stream named
/src/headerblock which contains a hash table of embedded
files to records describing them.

This patch adds this functionality, including the /NATVIS
option to lld-link.

Zachary Turner bbe23ae675 [lit] Rename lld and clang lit configs to end in .py
This follows in line with a previous patch of renaming LLVM's.

Working on these files is difficult in certain operating systems
and/or environments that don't like handling python code with a
non .py file extension.
