Summary
This PR will allow us to error on things of the sort:
"byte 0x01; store 0; int 1; load 0; +"
by keeping track of the scratch space as we assemble the program within each basic block.
Test Plan
Load/Store: Tested to make sure a load in the first block puts a uint64 on the stack and that load puts the type of whatever was last stored in that slot if a store was done in that block
Loads/Stores: Added test for loads when all the slots are the same type and put in a test for stores which makes sure it only sets slots to StackAny if the type is not the same as what's on the stack
