Thanks, i like it.

+/*
 void CodeGenFunction::EmitAlignmentAssumption(llvm::Value *PtrValue,
                                               QualType Ty, SourceLocation Loc,
                                               SourceLocation AssumptionLoc,

                                               llvm::Value *OffsetValue) {
   llvm::Value *TheCheck;
----------------
Just remove.

              << Arg->getSourceRange();
+    if (Result > (1 << 29ULL))
+      Diag(TheCall->getBeginLoc(), diag::warn_assume_align_too_big)
----------------
`(1ULL << 29ULL)`.
Is there some define for this somwhere, don't like magic numbers.
