    i386: Fix some -O0 avx2intrin.h and xopintrin.h intrinsic macros [PR94046]

    As the testcases show, the macros we have for -O0 for intrinsics that
require
    constant argument(s) should first cast the argument to the type the -O1+
    inline uses and afterwards to whatever type e.g. a builtin needs.
    The PR reported one which violated this, and I've grepped for all
double-casts
    and grepped out from that meaningful casts where the __m{128,256,512}{,d,i}
    first cast is cast to same sized __v* type and has the same kind of element
    type (float, double, integral).  These 7 macros were using different casts,
    and I've double checked them against the inline function types.
