<pre>If I try to generate an AST with clang::ParseAST(), it will end up removing any
previously-registered (fatal) signal handlers.
clang::ParseAST() should restore the original signal handlers on exit. But
before I can open a bug against clang, I believe the support for disabling and
restoring the original signal handler must be added to the Support libraries.
Please create an llvm::DisablePrettyStackTrace() which restores the original
signal handlers replaced, and/or a class to preserve this data if that makes
more sense.</pre>
