rebased.

@nikic it looks like there's a crash on the llvm-compile-time-tracker with the latest version (applying rewrites), but I was unable to reproduce this locally with various combinations of flags. What compiler/flags is used by the tracker to build the compiler used?

The log to the failure is http://llvm-compile-time-tracker.com/show_error.php?commit=d628e5e177b9a9dd4f279ce7c301fd312be0cfa7 in case you have any ideas.
