/* Note that an IRInst can be derived from, but when it derived from it's new members are IRUse
variables, and they in effect alias over the operands - and reflected in the operand count. There
_could_ be other members after these IRUse variables, but only a few types include extra data, and
these do not have any operands:
* IRConstant - Needs special-case handling
* IRModuleInst - Presumably we can just set to the module pointer on reconstruction
Note! That on an IRInst there is an IRType* variable (accessed as getFullType()). As it stands it
may NOT actually point to an IRType derived type. Its 'ok' as long as it's an instruction that can
be used in the place of the type. So this code does not bother to check if it's correct, and just
casts it.
