  Changed paths:
    M llvm/lib/Target/AArch64/GISel/AArch64PostLegalizerCombiner.cpp
    M llvm/test/CodeGen/AArch64/GlobalISel/postlegalizer-combiner-shuffle-splat.mir
    M llvm/test/CodeGen/AArch64/GlobalISel/select-dup.mir

  Log Message:
  -----------
  [AArch64][GlobalISel] Allow G_DUP for elements smaller than 32 B.

We select all of these via patterns now, so there's no reason to disallow this.

Update select-dup.mir to show that we correctly select the smaller types.
