    M llvm/test/Transforms/InstCombine/sincospi.ll

  Log Message:
  -----------
  [SimplifyLibCalls] Return Value from optimizeSinCosPi when making change

Or else InstCombine can incorrectly report that no change has been made.

This optimization doesn't really fit into InstCombine since it optimizes multiple instructions at once; there's likely a more comprehensive fix.
