Discard functions with landing pads
Discard functions with landing pads

This is a temporary measure during EH bring-up; methods with landing pads
will have their IR shown (if IR dumps are enabled), but then will be
discarded so we'll fall back to the other jit rather than choking on the
landing pads downstream.
