[Inliner] Don't inline functions with frameescape calls

Inlining such intrinsics is very difficult, since you need to
simultaneously transform many calls to llvm.framerecover and potentially
duplicate the functions containing them.  Normally this intrinsic isn't
added until EH preparation, which is part of the backend pass pipeline
after inlining.  However, if it were to get fed through the inliner,
this change will ensure that it doesn't break the code.
