Hi all,

I just found in MASK_ISA2_UNSET part, since AVX512BW is based on AVX512F, we
should add OPTION_MASK_ISA2_AVX512BW_UNSET to AVX512F for maintainence
convenience and logic correctness, or we will need to add all future ISAs based
on AVX512BW in both AVX512F and AVX512BW. This will be easily forgot and might
cause confusion.

Also remove the redundant ones in this change.

Regtested on x86_64-pc-linux-gnu. Ok for trunk?

BRs,
Haochen

gcc/ChangeLog:

	* common/config/i386/i386-common.cc (OPTION_MASK_ISA2_AVX512F_UNSET):
	Add OPTION_MASK_ISA2_AVX512BW_UNSET, remove
	OPTION_MASK_ISA2_AVX512BF16_UNSET and
	OPTION_MASK_ISA2_AVX512FP16_UNSET.
