Specifically: 1. We were tracking the stack allocation both in handleScopeInst and in the Stack. We should only track it in one of them. I also used this as an opportunity to make sure the code worked for non_nested code. 2. I made it so that we properly handle the end tracking part of the code so we handle the token/stack part of begin_apply correctly. I generalized the code so that we should handle non_nested stack allocations as well. I included tests that validated that we now handle this correctly.
