    * config/i386/i386.md (*floatunssi<mode>2_i387_with_xmm): New
    define_insn_and_split pattern, merged from *floatunssi<mode>2_1
    and corresponding splitters.  Zero extend general register
    or memory input operand to XMM temporary.  Enable for
    TARGET_SSE2 and TARGET_INTER_UNIT_MOVES_TO_VEC only.
    (floatunssi<mode>2): Update expander predicate.
