David Sherwood c02332a693 [CodeGen] Fix warning in getNode for EXTRACT_SUBVECTOR
Fix a warning in getNode() when extracting a subvector from a
concat vector. We can simply replace the call to getVectorNumElements
with getVectorMinNumElements as this follows the defined behaviour
for EXTRACT_SUBVECTOR.

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!
