  Changed paths:
    M llvm/lib/Target/AArch64/AArch64InstrGISel.td
    M llvm/test/CodeGen/AArch64/GlobalISel/select-rev.mir
    M llvm/test/CodeGen/AArch64/GlobalISel/select-trn.mir

  Log Message:
  -----------
  [AArch64][GlobalISel] Set hasSideEffects = 0 on custom shuffle opcodes

This was making it so that the instructions weren't eliminated in
select-rev.mir and select-trn.mir despite not being used.

Update the tests accordingly.
