    c/107305 - avoid ICEing with invalid GIMPLE input to the GIMPLE FE

    The GIMPLE FE was designed to defer semantic error checking to the
    GIMPLE IL verifier.  But that can end up causing spurious ICEs
    earlier and in fact it will report an internal error.  The following
    tries to improve the situation by explicitely calling into the
    verifier from the parser and intructing it to not ICE but instead
    zap the parsed body after an error is discovered.
