This helps lit unit test performance by a lot, especially on windows. The performance gain comes from launching one gtest executable for many subtests instead of one (this is the current situation).
The shards are executed by the test runner and the results are stored in the
json format supported by the GoogleTest. Later in the test reporting stage,
all test results in the json file are retrieved to continue the test results
summary etc.

This flag silents the build output of test-release.sh so that
it can be used in CI systems a bit better. It will still log
the build output to the log files but not echo it to stdout.

This lets the revert_checker.py get called with the -u option, which
formats the revert and reverted SHAs into handy URLs which point to the
LLVM reviews associated with those SHAs. This is useful for viewers to
look quickly at the changes made by SHAs that were potentially reverted.

It was already the case for CLI help, also support it for rst output. As a side
effect remove redundant (and sometime inconsistent!) value help from HelpText in
clang/Driver/Options.td.

1. Add comments to explain why we set `isAsmParserOnly` for XACQUIRE and XRELEASE
2. Check `X86Inst` in the constructor of `RecognizableInstrBase` so that
we can avoid the case where one of it's field is not initialized but
accessed by user. (e.g. in X86EVEX2VEXTablesEmitter.cpp)
3. Move `Rec` from `RecognizableInstrBase` to `RecognizableInstr` to reduce
size of `RecognizableInstrBase`
4. Remove out-of-date comments for shouldBeEmitted() (filter() was removed)
5. Add a basic field `IsAsmParserOnly` and remove the field
`ShouldBeEmitted` b/c we can deduce it w/ little overhead
In fact, an instruction can not be emitted to disassemble table when
`isAsmParserOnly` is true, so `isAsmParserOnly=true` implies
`ShouldBeEmitted=false`.
We check `isAsmParserOnly` in X86FoldTablesEmitter.cpp at a early stage
b/c none of them is foldable.
All LLVM backends use MCDisassembler as a base class for their
instruction decoders. Use "const MCDisassembler *" for the decoder
instead of "const void *". Remove unnecessary static casts.

CLANG_TOOLS_DIR holds the the current bin/ directory, maybe with a %(build_mode)
placeholder. It is used to add the just-built binaries to $PATH for lit tests.
In most cases it equals LLVM_TOOLS_DIR, which is used for the same purpose.
But for a standalone build of clang, CLANG_TOOLS_DIR points at the build tree
and LLVM_TOOLS_DIR points at the provided LLVM binaries.
Currently CLANG_TOOLS_DIR is set in clang/test/, clang-tools-extra/test/, and
other things always built with clang. This is a few cryptic lines of CMake in
each place. Meanwhile LLVM_TOOLS_DIR is provided by configure_site_lit_cfg().
This patch moves CLANG_TOOLS_DIR to configure_site_lit_cfg() and renames it:
- there's nothing clang-specific about the value
- it will also replace LLD_TOOLS_DIR, LLDB_TOOLS_DIR etc (not in this patch)
It also defines CURRENT_LIBS_DIR. While I removed the last usage of
CLANG_LIBS_DIR in e4cab4e24d1, there are LLD_LIBS_DIR usages etc that
may be live, and I'd like to mechanically update them in a followup patch.

It's unusual that BLAKE3/CMakeLists.txt just defines a list of
files that it injects into its parent scope. The list should either
be defined in llvm/lib/Support/CMakeLists.txt, or
llvm/lib/Support/BLAKE3/CMakeLists.txt should define an object
library.
This does the latter. It makes llvm/lib/Support/BLAKE3/CMakeLists.txt
more self-contained.
No behavior change.

This is legacy PM-specific, which is deprecated.
Uses of this should be replaced with a corresponding `-passes='print<foo>'`.

This reverts commit 7aea3ea8c3b33c9bb338d5d6c0e4832be1d09ac3 as it
breaks the buildbots.
I didn't see these failures in the pre-merge checks, looking into it.
Most intrinsics, especially "default" ones, will not call back into the
IR module. `nocallback` encodes this nicely. As it was not used before,
this patch also makes use of `nocallback` in the Attributor which
results in many more `norecurse` deductions.
Tablegen part is mechanical, test updates by script.
