[PATCH] An analysis to find external function pointers and trace their data flow

[Tom Roeder]

  I tried to request a reviewer earlier today, but I didn't see any email sent about it. Apologies in advance if I somehow missed it and this is effectively a duplicate email.

  Eric: this is a prerequisite for the implementation of Control-Flow Integrity (CFI) code we were discussing on llvmdev; this helps find external functions pointers that can cause false positives in CFI. Can you please take a look and tell me what you think? Or can you point me at the right person to review this if it's not you?
