When coloring EH funclets during WinEHPrepare, we should check that none of the involved funclet bundle operands refers to an invalid/out-of-scope funclet pad. This would lead to silent binary truncations later on.
For the time being users can demote the error into a warning by passing the `-no-funclet-bundle-errors` flag.
