This is a support patch for D69825 <https://reviews.llvm.org/D69825>.
It handles an exception in the same way as the global exception handler (same side-effect, print call stack & cleanup), and can return the exception code.
It enables `CrashRecoveryContext` exceptions by default (instead of disabled before) - however the exception handlers are lazily installed on the first creation of a `CrashRecoveryContext`.
