Gabe Black 91e24ba776 misc: Replace THE_ISA macro with IS_NULL_ISA.
Now all occurances of the THE_ISA macro which were being used to check
for anything other than the NULL_ISA have been eliminated. We still need
to be able to check whether the current ISA is the null ISA, but we
don't want to let any preprocessor checks back in which are based on
what the current ISA is.

This change removes the THE_ISA macro, and replaces it with IS_NULL_ISA
which evaluates to 1 if the ISA is null, and 0 if it isn't.
