Zachary Turner f228276262 [PDB] Resubmit "Support embedding natvis files in PDBs."
This was reverted several times due to what ultimately turned out
to be incompatibilities in our serialized hash table format.

Several changes went in prior to this to fix those issues since
they were more fundamental and independent of supporting injected
sources, so now that those are fixed this change should hopefully
pass.

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.

Alexander Richardson 8edd70b7c6 [ELF] Add llvm-readelf to the lit tool substitutions
Summary:
Some of the tests invoke llvm-readelf. This currently appears to work
probably because the LLVM binary directory is included in $PATH. However,
this is quite fragile so let's just make lit expand the full path.

Rui Ueyama 7c9ad29304 Remove "--full-shutdown" and instead use an environment variable LLD_IN_TEST.
We are running lld tests with "--full-shutdown" option because we don't
want to call _exit() in lld if it is running tests. Regular shutdown
is needed for leak sanitizer.

This patch changes the way how we tell lld that it is running tests.
Now "--full-shutdown" is removed, and LLD_IN_TEST environment variable
is used instead.

This patch enables full shutdown on all ports, e.g. ELF, COFF and wasm.
Previously, we enabled it only for ELF.

Igor Kudrin 85e68a6601 [lit] Respect LLVM_LIT_TOOLS_DIR when looking for 'tar' on Windows.
Changes in D38977 expect 'tar' to be found in one of PATH directories.
On Windows, one might opt to use LLVM_LIT_TOOLS_DIR rather than add MSYS
tools directory to the PATH. In that case, tests for lld failed on run.

Zachary Turner ad5997e87a [lit] Raise the logic for enabling clang & lld substitutions to llvm.
This paves the way for other projects which might /use/ clang or
lld but not necessarily need to the full set of functionality
available to clang and lld tests to be able to have a basic set
of substitutions that allow a project to run the clang or lld
executables.

Zachary Turner 96b04b68ed [lit] Improve tool substitution in lit.
This addresses two sources of inconsistency in test configuration
files.

1. Substitution boundaries.  Previously you would specify a
   substitution, such as 'lli', and then additionally a set
   of characters that should fail to match before and after
   the tool.  This was used, for example, so that matches that
   are parts of full paths would not be replaced.  But not all
   tools did this, and those that did would often re-invent
   the set of characters themselves, leading to inconsistency.
   Now, every tool substitution defaults to using a sane set
   of reasonable defaults and you have to explicitly opt out
   of it.  This actually fixed a few latent bugs that were
   never being surfaced, but only on accident.

2. There was no standard way for the system to decide how to
   locate a tool.  Sometimes you have an explicit path, sometimes
   we would search for it and build up a path ourselves, and
   sometimes we would build up a full command line.  Furthermore,
   there was no standardized way to handle missing tools.  Do we
   warn, fail, ignore, etc?  All of this is now encapsulated in
   the ToolSubst class.  You either specify an exact command to
   run, or an instance of FindTool('<tool-name>') and everything
   else just works.  Furthermore, you can specify an action to
   take if the tool cannot be resolved.

Zachary Turner 0d36b657b9 [lit] Refactor out some more common lit configuration code.
debuginfo-tests has need to reuse a lot of common configuration
from clang and lld, and in general it seems like all of the
projects which are tightly coupled (e.g. lld, clang, llvm, lldb,
etc) can benefit from knowing about one other.  For example,
lldb needs to know various things about how to run clang in its
test suite.  Since there's a lot of common substitutions and
operations that need to be shared among projects, sinking this
up into LLVM makes sense.

In addition, this patch introduces a function add_tool_substitution
which handles all the dirty intricacies of matching tool names
which was previously copied around the various config files.  This
is now a simple straightforward interface which is hard to mess
up.
