Sander de Smalen 6bf806b3e2 [AArch64] ACLE: Fix issue for mismatching enum types with builtins.
This patch fixes an issue with the SVE prefetch and qinc/qdec intrinsics
that take an `enum` argument, but where the builtin prototype encodes
these as `int`. Some code in SemaDecl found the mismatch and chose
to forget about the builtin altogether, which meant that any future
code using that builtin would fail. The code that forgets about the
builtin was actually obsolete after D77491 and should have been removed.
This patch now removes that code.

This patch also fixes another issue with the SVE prefetch intrinsic
when built with C++, where the builtin didn't accept the correct
pointer type, which should be `const void *`.

Sander de Smalen 672f673004 [SVE] Remove checks for warnings in scalable-vector tests.
After D98856 these tests will by default break (fatal_error) if any of
the wrong interfaces are used, so there's no longer a need to have a
RUN line that checks for a warning message emitted by the compiler.

Sander de Smalen fabe67728e [AArch64][SVE] Enable __ARM_FEATURE_SVE macros.
This patch enables the following macros when their corresponding
target attributes are set:
      __ARM_FEATURE_SVE (+sve)
      __ARM_FEATURE_SVE2 (+sve2)
      __ARM_FEATURE_SVE2_AES (+sve2-aes)
      __ARM_FEATURE_SVE2_BITPERM (+sve2-bitperm)
      __ARM_FEATURE_SVE2_SHA3 (+sve2-sha3)
      __ARM_FEATURE_SVE2_SM4 (+sve2-sm4)

This implies that the base SVE and SVE2 ACLE (00bet2) are now feature
complete, meaning that all intrinsics are implemented in LLVM and Clang.

Disclaimer:

To implement the ACLE we have had to fix up many parts of LLVM to make it
support scalable vectors. We have also used many target-specific intrinsics
to reduce reliance on parts of LLVM where we know scalable vectors may
not yet be handled properly (e.g. some transformation might drop the
'scalable' flag on a vector type). While we've done a best effort with
the limited testing that is available to us, we're still working to improve the
stability of the implementation. Additionally, Clang may print warnings
that code may have miscompiled. We find this often to be a false alarm
where the wrong interfaces have been used in LLVM and where resulting
code is not actually incorrect. However, this warrants a bug report
and investigation. If you find any bugs or issues, please raise them on
bugs.llvm.org and let us know!

David Sherwood 3cfd74e64b [SVE] Add checks for no warnings in SVE tests
There are now quite a few SVE tests in LLVM and Clang that do not
emit warnings related to invalid use of EVT::getVectorNumElements()
and VectorType::getNumElements(). For these tests I have added
additional checks that there are no warnings in order to prevent
any future regressions.
