    x86: Compile some BF16 tests with -mno-avx512bf16 -mno-avxneconvert

    Compile some BF16 tests with -mno-avx512bf16 -mno-avxneconvert to avoid

    FAIL: gcc.target/i386/sse2-bfloat16-scalar-typecheck.c (test for excess
errors)
    FAIL: gcc.target/i386/vect-bfloat16-typecheck_1.c (test for excess errors)
    FAIL: gcc.target/i386/vect-bfloat16-typecheck_2.c (test for excess errors)

    with errors like

    sse2-bfloat16-scalar-typecheck.c:16:1: warning: â__bfloat16â is
redefined from typedef âshortâ to real â__bf16â since GCC 13.1, be
careful of implicit conversion between â__bf16â and âshortâ; an
explicit bitcast may be needed here

    when AVXNECONVERT or AVX512BF16 are enabled by default.

            Add -mno-avx512bf16 -mno-avxneconvert.
