These directives are legal everywhere. They can be used to
patch away BRIG entries at the binary level.
Also add extra error detection for zeroed regions: make sure
the byteCount field is never zero.
The call code still failed a few PRM test cases. Now all PRM
branch cases pass again.

This patch uses global rather than member operators for wide-int.h,
so that the first operand can be a non-wide-int type.
The patch also removes the and_not and or_not member functions.
It was already inconsistent to have member functions for these
two operations (one of which was never used) and not other wi::
ones like udiv. After the operator change, we'd have the additional
inconsistency that "non-wi & wi" would work but "non-wi.and_not (wi)"
wouldn't.

Currently we have two patterns for every conditional jump: one jumping
if some condition is met, and the other jumping if it is not met. We
don't need that second form because all our conditions have an opposite
already, and the generic code can deal with that just fine.
This patch deletes that second form. We generated it directly in one
case; adjusted here.
