Closes #33577, a bug with ExtractScopeDeclarationsFromDestructuring and codegen when a function param is reassigned.
Small cosmetic win, found this when i was looking at some code internally with lots of cases that all share the same logic. Previously, all the but last one would have an empty block.
We now have `HIRFunction.returns: Place` as well as `returnType: Type`. I want to add additional return information, so as a first step i'm consolidating everything under an object at `HIRFunction.returns: {place: Place}`. We use the type of this place as the return type. Next step is to add more properties to this object to represent things like the return kind.
