    x86: Disable AVX512BW for pr70325.c
    
    __builtin_ia32_storedquqi256_mask is available when both AVX512VL and
    AVX512BW are enabled.  Disable AVX512BW for pr70325.c to avoid
    
    FAIL: gcc.target/i386/pr70325.c (test for excess errors)
    FAIL: gcc.target/i386/pr70325.c  (test for warnings, line 11)
    
    due to the generated error:
    
    .../gcc.target/i386/pr70325.c:11:37: warning: passing argument 1 of ‘__builtin_ia32_storedquqi256_mask’ from incompatible pointer type [-Wincompatible-pointer-types]
    .../gcc.target/i386/pr70325.c:11:37: note: expected ‘char *’ but argument is of type ‘C *’ {aka ‘__vector(32) char *’}
    
    vs the expected error
    
    .../gcc.target/i386/pr70325.c: In function ‘f’:

    when AVX512BW is enabled by default.
