    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 ra=
ther
    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.
