i386: Support partial vectorized FMA for V2BF/V4BF
This patch introduces support for vectorized FMA operations for bf16 types in
V2BF and V4BF modes on the i386 architecture. New mode iterators and
define_expand entries for fma, fnma, fms, and fnms operations are added in
mmx.md, enhancing the i386 backend to handle these complex arithmetic operations.
gcc/ChangeLog:
* config/i386/mmx.md (TARGET_MMX_WITH_SSE): New mode iterator VBF_32_64
(fma<mode>4): define_expand for V2BF/V4BF fma<mode>4.
(fnma<mode>4): define_expand for V2BF/V4BF fnma<mode>4.
(fms<mode>4): define_expand for V2BF/V4BF fms<mode>4.
(fnms<mode>4): define_expand for V2BF/V4BF fnms<mode>4.
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx10_2-partial-bf-vector-fma-1.c: New test.
