i386: Add bf8 -> fp16 intrin
Since BF8 and FP16 have same bits for exponent, the type conversion
between them is just a cast for fraction part. We will use a sequence
of instrctions instead of new instructions to do that. For convenience,
intrins are also provided.
gcc/ChangeLog:
* config/i386/avx10_2-512convertintrin.h
(_mm512_cvtpbf8_ph): New.
(_mm512_mask_cvtpbf8_ph): Ditto.
(_mm512_maskz_cvtpbf8_ph): Ditto.
* config/i386/avx10_2convertintrin.h
(_mm_cvtpbf8_ph): Ditto.
(_mm_mask_cvtpbf8_ph): Ditto.
(_mm_maskz_cvtpbf8_ph): Ditto.
(_mm256_cvtpbf8_ph): Ditto.
(_mm256_mask_cvtpbf8_ph): Ditto.
(_mm256_maskz_cvtpbf8_ph): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx10_2-512-convert-1.c: Add tests for new
intrin.
* gcc.target/i386/avx10_2-convert-1.c: Ditto.
