i386: Fix AVX512 intrin macro typo

There are several typo in AVX512 intrins macro define. Correct them to solve
errors when compiled with -O0.

gcc/ChangeLog:

	* config/i386/avx512dqintrin.h
	(_mm_mask_fpclass_ss_mask): Correct operand order.
	(_mm_mask_fpclass_sd_mask): Ditto.
	(_mm256_maskz_reduce_round_ss): Use __builtin_ia32_reducess_mask_round
	instead of __builtin_ia32_reducesd_mask_round.
	(_mm_reduce_round_sd): Use -1 as mask since it is non-mask.
	(_mm_reduce_round_ss): Ditto.
	* config/i386/avx512vlbwintrin.h
	(_mm256_mask_alignr_epi8): Correct operand usage.
	(_mm_mask_alignr_epi8): Ditto.
	* config/i386/avx512vlintrin.h (_mm_mask_alignr_epi64): Ditto.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/avx512bw-vpalignr-1b.c: New test.
	* gcc.target/i386/avx512dq-vfpclasssd-1b.c: Ditto.
	* gcc.target/i386/avx512dq-vfpclassss-1b.c: Ditto.
	* gcc.target/i386/avx512dq-vreducesd-1b.c: Ditto.
	* gcc.target/i386/avx512dq-vreducess-1b.c: Ditto.
	* gcc.target/i386/avx512vl-valignq-1b.c: Ditto.
