    AArch64: Rewrite simd move immediate patterns to new syntax

    This rewrites the simd MOV patterns to use the new compact syntax.
    No change in semantics is expected.  This will be needed in follow on
patches.

    This also merges the splits into the define_insn which will also be nee=
ded
soon.
