* config/i386/sse.md (<sse4_1>_round<ssemodesuffix><avxsizesuffix>):
Limit 1st alternative to noavx isa, split 2nd alternative into one
noavx and one avx alternative, use *x and Bm in the former and
x and m in the latter.
* config/i386/sse.md (vec_set<mode>_0): Use sse4_noavx isa instead
of sse4 for the first alternative, drop %v from the template
and d operand modifier. Split second alternative into one sse4_noavx
