Thanks for sending this out!

Instead of the dynamic lookup of that symbol, what do you think about passing in the function via a normal api? That way, the type checker and linker help us keep things working; dynamic lookup is always a bit subtle and hard to grep for. (llvm-cs wouldn't know about the current use, for example.) See https://reviews.llvm.org/D69848 for a rough sketch.

For robust crash handling, I figured on non-win we'd have a signal handler that on signal self-execs with a "actually, do use a cc1 process" and then use the existing crash machinery, but maybe that's not needed.
