[PATCH] D14420: [Polly][WIP] Add polly profitable source annotation

[Johannes Doerfert via llvm-commits]

jdoerfert added reviewers: grosser, Meinersbur.
jdoerfert added a subscriber: Polly.

  Profitable annotations can be placend in the source via:
    __builtin_assume(__polly_profitable == X)
  where X has to be the constant 0 (=unprofitable) or 1 (=profitable) and
  __polly_profitable a global variable.

  If multiple annotations dominate a region, the number of
  "profitable"/"unprofitable" annotations is used to decide what to do.

  -- Missing unit tests
