i386: Fix the pmovzx SSE4.1 define_insn_and_split patterns [PR98670]
I've made two mistakes in the *sse4_1_zero_extend* define_insn_and_split
patterns. One is that when it uses vector_operand, it should use Bm rather
than m constraint, and the other one is that because it is a post-reload
splitter it needs isa attribute to select which alternatives are valid for
which ISAs. Sorry for messing this up.

Use Bm instead of m for non-avx. Add isa attribute.
