Currently IL verification errors trigger "confused by earlier errors"
messages with a release compiler but compiling with -fchecking.
That is because those use error() before internal_error.
This precludes useful things like emergency IL dump in dump files.
Thus the following - change CHECKING_P to flag_checking.
Any objections?
