Message:
Hey,
so this is a much cleaner approach than having control instructions with
side
effects, since we can still have a simulate between checking the condition
and
branching.
Description:
Split HCompareGeneric in a test and a branch part.
A similar approach can now be taken with all other branching instructions.
