[PATCH] [AArch64]Add support to copy Q register tuples QPair, QTriple, QQuad in copyPhyReg

[Hao Liu]

  Hi Tim,

  Sorry for the misleading. This patch is duplicated to D2473. We have test cases for D tuple copy, but the test cases are too large (hundreds of lines) and difficult to be simplified . So I think there is no need to add such test cases. As D tuple copy is similar to Q tuple copy, we don't need to worry about if there is some problems.

  I've committed the code in http://llvm.org/viewvc/llvm-project?view=revision&revision=198682.

  Thanks,
  -Hao
