    i386: Keep _ep[i|u]{32,64} names of scalar SAT CVT intrinsics [PR126581]

    r16-9456 renamed the AVX10.2 scalar SAT CVT intrinsics to the _[i|u]{32=
,64}
    suffix and was backported to releases/gcc-15 and releases/gcc-16.
    Within a release series the old names have to keep working, so add them
    back as aliases.
