This reverts commit 3f76260dc0674cc0acb25f550a0f0c594cf537ea.
Breaks at least these tests on Windows:
Clang :: Driver/clang-offload-bundler.c
Clang :: Driver/clang-offload-wrapper.c
And belatedly merge r353268 / r353269.
test/Driver/wasm-toolchain-lto.c currently requires getLLVMRevision()
to return something non-empty to pass. That's hopefully temporary,
but making Version.cpp work is probalby a good idea regardless.
(Note its contents will by default usually be out-of-date, because
llvm_allow_tardy_revision defaults to false.)
For lldb and dsymutil, the command guide is essentially a copy of its
help output generated by libOption. Making sure the two stay in sync is
tedious and error prone. Given that we already generate the help from a
tablegen file, we might as well generate the RST as well.
This adds a tablegen backend for generating Sphinx/RST command guides
from the tablegen file.

This header fragment is useful on its own for any consumer that wants
to use custom instruction profile runtime with the LLVM instrumentation.
The concrete use case is in Fuchsia's kernel where we want to use
instruction profile instrumentation, but we cannot use the compiler-rt
runtime because it's not designed for use in the kernel environment.
This change allows installing this header as part of compiler-rt.

Clone+exec death test allocates a single page of stack to run chdir + exec on.
This is not enough when gtest is built with ASan and run on particular
hardware.
With ASan on x86_64, ExecDeathTestChildMain has frame size of 1728 bytes.
Call to chdir() in ExecDeathTestChildMain ends up in
_dl_runtime_resolve_xsavec, which attempts to save register state on the stack;
according to cpuid(0xd) XSAVE register save area size is 2568 on my machine.
This results in something like this in all death tests:
Result: died but not with expected error.

This was added to update_test_checks.py in D68819 and I believe having it
in update_cc_test_checks.py is also useful.

Summary:
Add a function common.parse_commandline_args() that adds options common
to all tools (--verbose and --update-only) and returns the parsed
commandline arguments. I plan to use the shared parsing of --verbose in a
follow-up commit to remove most of the `if args.verbose:` checks in the
scripts.

Summary:
This also changes the test-release.sh script to build using the monorepo
layout instead of copying sub-projects into llvm/tools or llvm/projects.

* Implements scalable size queries for MVTs, split out from D53137.
* Contains a fix for FindMemType to avoid using scalable vector type
to contain non-scalable types.
* Explicit casts for several places where implicit integer sign
changes or promotion from 32 to 64 bits caused problems.
* CodeGenDAGPatterns will treat scalable and non-scalable vector types
as different.

Summary:
Using c-index-test is fragile since it does not parse all the clang
arguments that are used in the RUN: line. This can result in incorrect
mangled names that do not match any of the generated IR.
For example macOS triples include a leading underscore (which was handled
with a hack in the current script). For the CHERI target we have added
new qualifiers which affect C++ name mangling, but will be included added
by update_cc_test_checks since it parses the source file with the host
triple because it ignores the -triple= argument passed to clang -cc1.
Using the new feature of including the mangled name in the JSON AST dump
(see D69564), we can parse the output of the RUN: command with
"-fsyntax-only -ast-dump=json" appended.
This should make the script less fragile and also forks one process less.

Fail early, when we discover no tests at all, or filter out all of them.
There is also `--allow-empty-runs` to disable test to allow workflows
like `LIT_FILTER=abc ninja check-all`. Apparently `check-all` invokes
lit multiple times if certain projects are enabled, which would produce
unwanted "empty runs". Specify via `LIT_OPTS=--allow-empty-runs`.
There are 3 causes for empty runs:
1) No tests discovered. This is always an error. Fix test suite config
or command line.
2) All tests filtered out. This is an error by default, but can be
suppressed via `--alow-empty-runs`. Should prevent accidentally
passing empty runs, but allow the workflow above.
3) The number of shards is greater than the number of tests. Currently,
this is never an error. Personally, I think we should consider
making this an error by default; if this happens, you are doing
something wrong. I added a warning but did not change the behavior,
since this warrants more discussion.
