Dimitry Andric b5e99283f4 Pull in r271548 from upstream llvm trunk (by me): 
Only attempt to detect AVG if SSE2 is available

  Summary:
  In PR29973 Sanjay Patel reported an assertion failure when a certain
  loop was optimized, for a target without SSE2 support.  It turned out
  this was because of the AVG pattern detection introduced in rL253952.

  Prevent the assertion failure by bailing out early in
  `detectAVGPattern()`, if the target does not support SSE2.

  Also add a minimized test case.

  Reviewers: congh, eli.friedman, spatel

  Subscribers: emaste, llvm-commits

  Differential Revision: http://reviews.llvm.org/D20905

This should fix assertion failures ("Requires at least SSE2!") when
building the games/0ad port with CPUTYPE=pentium3.
