i386: Disable SImode/DImode moves from/to mask regs without avx512bw [PR118067]
SImode and DImode moves from/to mask registers are valid only with AVX512BW,
so mark relevant alternatives in *movsi_internal and *movdi_internal as such.
Even with the patch, the testcase still fails, but now with:
pr118067.c: In function ‘foo’:
pr118067.c:13:1: internal compiler error: maximum number of generated reload insns per insn achieved (90)
