This PR merges C functions used by
newhashandtoreexpinstructions into one for each of them.When we introduce stack maps, we will need to write a
JITFramefor every C call, even if multiple calls share the sameFrameState. Calling fewer C functions allows us to reduce not only pushes/pops but alsoJITFramewrites.
