i386: Fix vfpclassph non-optimizied intrin

The intrin for non-optimized got a typo in mask type, which will cause
the high bits of __mmask32 being unexpectedly zeroed.

The test does not fail under O0 with current 1b since the testcase is
wrong. We need to include avx512-mask-type.h after SIZE is defined, or
it will always be __mmask8. That problem also happened in AVX10.2 testcases.
I will write a seperate patch to fix that.

gcc/ChangeLog:

	* config/i386/avx512fp16intrin.h
	(_mm512_mask_fpclass_ph_mask): Correct mask type to __mmask32.
	(_mm512_fpclass_ph_mask): Ditto.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/avx512fp16-vfpclassph-1c.c: New test.
