llvm-6502/test/Transforms/DeadStoreElimination
Pete Cooper 2d32b86543 DeadStoreElimination can now trim the size of a store if the end of it is dead.
Only currently done if the later store is writing to a power of 2 address or 
has the same alignment as the earlier store as then its likely to not break up
large stores into smaller ones
