Summary:
This would have been marginally useful to me during/for rG7ea46aee3670981827c04df89b2c3a1cbdc7561b.
With ongoing migration to representing assumes via operand bundles on the assume, this will be gradually more useful.

Summary: This is a complementary patch to D82100 since the aix builbot is still running the unsupported test shtest-format-argv0. Add system-aix to the sub llvm-lit config.

This fixes the build of compiler-rt on macOS when _not_ using
clang_base_path in args.gn: Xcode clang knows where to find the
SDK, but regular clang doesn't and needs a -isysroot parameter.
We correctly add that parameter when clang_base_path is set,
but else we omit it. If clang_base_path was not set, we also
didn't add the flag for stage2_unix_toolchain() when we build
compiler-rt with just-built clang.
Make stage2_unix_toolchain() use clang_base_path instead of setting
cc / cxx. It's less code, and it gets things like this right.
Instead of detecting it automatically (in libc++) and relying on
_LIBCXXABI_NO_EXCEPTIONS being set explicitly (in libc++abi), always
detect whether exceptions are enabled automatically.
This commit also removes support for specifying -D_LIBCPP_NO_EXCEPTIONS
and -D_LIBCXXABI_NO_EXCEPTIONS explicitly -- those should just be inferred
from using -fno-exceptions (or an equivalent flag).
Allowing both -D_FOO_NO_EXCEPTIONS to be provided explicitly and trying
to detect it automatically is just confusing, especially since we did
specify it explicitly when building libc++abi. We should have only one
way to detect whether exceptions are enabled, but it should be robust.
Summary:
Follow up to D81736. Move getOpenMPDirectiveKind, getOpenMPClauseKind, getOpenMPDirectiveName and
getOpenMPClauseName to the new tablegen code generation. The code is generated in a new file named OMP.cpp.inc

In RISC-V vector extension, users could group multiple vector registers
as one pseudo register. In mixed width operations, users could use
partial vector registers to reduce the register pressure. The parameter
to control register grouping and partial use is called LMUL. LMUL is a
part of the type. So, we have a bunch of vector types. In order to
support all these types, we need new MVT types in LLVM. In this patch, I
added several MVT types that are used in RISC-V vector implementation.
This is a standalone patch for MVT types without RISC-V related implementation.

Separate introduction of IntrNoFree property as suggested in D70365

`FILECHECK_OPTS` was implemented so that a test runner, such as CI,
can specify FileCheck debugging options, such as `-v` and `-vv`.
However, if a test suite has a FileCheck call that already specifies
`-v` or `-vv`, then that call will fail if `FILECHECK_OPTS` also
specifies it.
For `-vv`, this problem already exists:
`clang/test/CodeGen/aarch64-v8.2a-fp16-intrinsics-constrained.c`
It's not yet clear if the `-vv` in that test was intentional, but this
usage shouldn't fail anyway. It's already true that FileCheck permits
`-vv` and `-v` together even though `-vv` implies `-v`.
Compare D70784, which fixed the same problem for `-dump-input`.

This change includes the following:
- Add additional information in the relevant table-gen files to encode
the necessary information to automatically parse the argument into a
CompilerInvocation instance and to generate the appropriate command
line argument from a CompilerInvocation instance.
- Extend OptParserEmitter to emit the necessary macro tables as well as
constant tables to support parsing and generating command line
arguments for options that provide the necessary information.
- Port some options to use this new system for parsing and generating
command line arguments.

Summary:
As discussed previously when landing patch for OpenMP in Flang, the idea is
to share common part of the OpenMP declaration between the different Frontend.
While doing this it was thought that moving to tablegen instead of Macros will also
give a cleaner and more powerful way of generating these declaration.
This first part of a future series of patches is setting up the base .td file for
DirectiveLanguage as well as the OpenMP version of it. The base file is meant to
be used by other directive language such as OpenACC.
In this first patch, the Directive and Clause enums are generated with tablegen
instead of the macros on OMPConstants.h. The next pacth will extend this
to other enum and move the Flang frontend to use it.

These are documented as using modrm byte of 0xe8, 0xf0, and 0xf8
respectively. But hardware ignore bits 2:0. So 0xe9-0xef is treated
the same as 0xe8. Similar for the other two.
Fixing this required adding 8 new formats to the X86 instructions
to convey this information. Could have gotten away with 3, but
adding all 8 made for a more logical conversion from format to
modrm encoding.
I renumbered the format encodings to keep the register modrm
formats grouped together.
