but that defines macros with non-reserved names that should not be
defined in ISO C++. Only include the C header for non-strict modes, or
for pre-C++11 (because C++98 doesn't mention <complex.h> at all).

Also add extra error detection for zeroed regions: make sure

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.
