[sve][acle] Add some C intrinsics for brain float types. Summary: The following intrinsics has been added: svuint16_t svcnt[_bf16]_m(svuint16_t inactive, svbool_t pg, svbfloat16_t op) svuint16_t svcnt[_bf16]_x(svbool_t pg, svbfloat16_t op) svuint16_t svcnt[_bf16]_z(svbool_t pg, svbfloat16_t op) svbfloat16_t svtbl[_bf16](svbfloat16_t data, svuint16_t indices) svbfloat16_t svtbl2[_bf16](svbfloat16x2_t data, svuint16_t indices) svbfloat16_t svtbx[_bf16](svbfloat16_t fallback, svbfloat16_t data, svuint16_t indices) Reviewers: c-rhodes, kmclaughlin, efriedma, sdesmalen, ctetreau Subscribers: tschuett, hiraditya, rkruppe, psnobl, cfe-commits, llvm-commits Tags: #clang, #llvm Differential Revision: https://reviews.llvm.org/D82429

// REQUIRES: aarch64-registered-target
[sve][acle] Enable feature macros for SVE ACLE extensions. Summary: The following feature macros have been added: __ARM_FEATURE_SVE_BF16 __ARM_FEATURE_SVE_MATMUL_INT8 __ARM_FEATURE_SVE_MATMUL_FP32 __ARM_FEATURE_SVE_MATMUL_FP64 The driver has been updated to enable them accordingly to the value of the target feature passed at command line. The SVE ACLE tests using the macros have been modified to work with the target feature instead of passing the macro at command line.
