Jun Ma 599b2f0037 [AArch64][SVE] Handle svbool_t VLST <-> VLAT/GNUT conversion
According to https://godbolt.org/z/q5rME1naY and acle, we found that
there are different SVE conversion behaviours between clang and gcc. It turns
out that llvm does not handle SVE predicates width properly.

This patch 1) checks SVE predicates width rightly with svbool_t type.
2) removes warning on svbool_t VLST <-> VLAT/GNUT conversion.
3) disables VLST <-> VLAT/GNUT conversion between SVE vectors and predicates
due to different width.

Thomas Lively db7efcab7d [WebAssembly] Remove clang builtins for extract_lane and replace_lane
These builtins were added to capture the fact that the underlying Wasm
instructions return i32s and implicitly sign or zero extend the extracted lanes
in the case of the i8x16 and i16x8 variants. But we do sufficient optimizations
during code gen that these low-level details do not need to be exposed to users.

This commit replaces the use of the builtins in wasm_simd128.h with normal
target-independent vector code. As a result, we can switch the relevant
intrinsics to use functions rather than macros and can use more user-friendly
return types rather than trying to precisely expose the underlying Wasm types.
Note, however, that the generated LLVM IR is no different after this change.

This commit adds supports for clang to remap macOS availability attributes that have introduced,

The mappings in the SDKSettings json file will also be used in the clang driver for the driver

Matheus Izvekov 1d68ecafd6 [clang] fix oops: enable implicit moves in MSVC compatibility mode
When disabling simpler implicit moves in MSVC compatibility mode as
a workaround in D105518, we forgot to make the opposite change and
enable regular (P1825) implicit moves in the same mode.

As a result, we were not doing any implicit moves at all. OOPS!

This fixes it and adds test for this.

This is a fix to a temporary workaround, there is ongoing
work to replace this, applying the workaround only to
system headers and the ::stl namespace.

Alex Lorenz c68f247275 [clang-scan-deps] ignore top-level module dependencies that aren't actually imported
Whenever -fmodule-name=top_level_module name is parsed, and clang actually tries to
import top_level_module, the headers are imported textually and the module isn't actually
built. However, the dependency scanner could still record it as a potential dependency
if the module was reimported and thus recorded by the preprocessor callbacks.
This change avoids collecting this kind of module as a dependency by verifying that we don't
collect top level modules without actual PCM files.

when the warning is triggered by a system header and adds

Amy Kwan 356300a351 [NFC][PowerPC] Update builtins-ppc-altivec.c to be run under `-faltivec-src-compat=mixed`
This patch adds the `-faltivec-src-compat=mixed` option to the
`builtins-ppc-altivec.c` test.

Currently, the default for `-faltivec-src-compat` is `mixed`. The reason we
explicitly specify `mixed` to the RUN lines of this test is because eventually,
the default will set to `xl`.

Having the default as `xl` changes the CHECKs of this test slightly, as it
reorders some of the `vector bool` and `vector pixel` CHECKs (since under the
`xl` option, `vector bool` and `vector pixel` are treated in the same way as
other vector scalars). Explicitly specifying `mixed` ensures that we are testing
pre-existing Clang behaviour.
