    i386: Fix missed APX_NDD check for shift/rotate expanders [PR 112943]

    The ashl/lshr/ashr expanders calls ix86_expand_binary_operator, while
    they will be called for some post-reload split, and TARGET_APX_NDD is
    required for these calls to avoid force-load to memory at postreload
    stage.

    gcc/ChangeLog:

            PR target/112943
            * config/i386/i386.md (ashl<mode>3): Add TARGET_APX_NDD to
            ix86_expand_binary_operator call.
            (<insn><mode>3): Likewise for rshift.
            (<insn>di3): Likewise for DImode rotate.
            (<insn><mode>3): Likewise for SWI124 rotate.
