Handle exceptions thrown while parsing lazy functions for inlining.
We currently leave the exception as pending without returning a Failure::Exception() value. This is either caught immediately if running with --debug-code, or caught later by an assert in debug mode.
This change makes the pending exception be cleared before returning from the failed optimization attempt.
