[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!
