aarch64: FEAT_SVE_BFSCALE support
Add support for the `SVE_BFSCALE` architecture extension.
gcc/ChangeLog:
* doc/invoke.texi: Document `+sve-bfscale` flag.
* config/aarch64/aarch64.h (TARGET_SVE_BFSCALE): New macro.
* config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins):
Define `__AARCH64_FEATURE_SVE_BFSCALE`.
* config/aarch64/aarch64-sve-builtins-base.cc: Skip constant
folding for floating-point or unpredicated multiplications.
* config/aarch64/aarch64-sve-builtins-sve2.def: New `SVE_FUNCTION`s.
* config/aarch64/aarch64-sve.md: Modify insns for
`SVE_COND_FP_BINARY_INT` to handle BF16 modes.
* config/aarch64/aarch64-sve2.md
(@aarch64_sve_<optab><mode>, @aarch64_sve_<optab><mode>_single): New insn for `BFSCALE`.
Modify insns for `UNSPEC_FSCALE` to handle BF16 modes.
* config/aarch64/iterators.md (SVE_FULL_F_SCALAR): Add `VNx8BF` to iterator.
(SVE_FULL_F_BFSCALE): New iterator.
(SVE_Fx24_BFSCALE): New iterator.
(SVE_BFx24): New iterator.
(UNSPEC_FMUL): New unspec.
(V_INT_EQUIV): Add entries for BF16 modes.
(b): Add entries for scalar float modes.
(is_bf16): Add entries for BF16 modes and reformat.
(SVSCALE_SINGLE_INTARG): Likewise.
(SVSCALE_INTARG): Likewise.
(SVE_FP_MULL): New iterator.
gcc/testsuite/ChangeLog:
* lib/target-supports.exp: Add `sve-bfscale` to `sve_exts`.
* gcc.target/aarch64/pragma_cpp_predefs_4.c: Add test for `__ARM_SVE_FEATURE_BFSCALE`.
* gcc.target/aarch64/sme2/acle-asm/mul_bf16_x2.c: New test.
* gcc.target/aarch64/sme2/acle-asm/mul_bf16_x4.c: New test.
* gcc.target/aarch64/sme2/acle-asm/scale_bf16_x2.c: New test.
* gcc.target/aarch64/sme2/acle-asm/scale_bf16_x4.c: New test.
