    fix _mm512_{,mask_}cmp*_p[ds]_mask at -O0 [PR96174]

    The _mm512_{,mask_}cmp_p[ds]_mask and also _mm_{,mask_}cmp_s[ds]_mask
    intrinsics have an argument which must have a constant passed to it
    and so use an inline version only for ifdef __OPTIMIZE__ and have
    a #define for -O0.  But the _mm512_{,mask_}cmp*_p[ds]_mask intrinsics
    don't need a constant argument, they are essentially the first
    set with the constant added to them implicitly based on the comparison
    name, and so there is no #define version for them (correctly).
    But their inline versions are defined in between the first and s[ds]
    set and so inside of ifdef __OPTIMIZE__, which means that with -O0
    they aren't defined at all.

    This patch fixes that by moving those after the #ifdef __OPTIMIZE #else
    use #define #endif block.
