[PATCH] [PATCH][AArch64]Pattern match failures for truncate store and extend load

[David Blaikie]

  The same feedback I gave on http://llvm-reviews.chandlerc.com/D2348

  "Hi Hao,

  Generally it's accepted that if you sent code out for review it's
  because you aren't comfortable/confident in the change to submit it
  with post-commit review. In that case, you are committed to waiting
  for feedback to increase your confidence until it is ready to be
  committed. Sending something for review, then committed in the absence
  of feedback is a red flag - it looks like "I'm not sure about this
  patch, but I'm going to push it through anyway because I can't wait
  long enough for review".

  Is there some reason you originally thought this deserved pre-commit
  review but don't believe that's the case anymore?"
