This patch adds support for producing additional diagnostic information upon a clang crash. Specifically, the compile is rerun to generate preprocessed source and a message is emitted showing all the command-line options needed to reproduce the problem. The user is asked to submit a radar/bug report and attach this additional information. Also, I tested things by hard coding the verifier pass to fail, but I was hoping someone could suggest a more robust means of testing prior to committing.
This is for <rdar://problem/9575623>. Regards, Chad
