x86: change AVX512VL handling in cpu_flags_match()

In order to add an AVX512F counterpart to the present AVX checking, it
is better to move the AVX512VL check out of the conditional it's
currently in.

* config/tc-i386.c (cpu_flags_match): Move AVX512VL check ahead.

* config/tc-i386.c (CPU_FLAGS_32BIT_MATCH): Delete.
