The following page has been changed by George Timoshenko:

New page:
Memory optimization pass reduces the number of operations with memory by removing redundant
loading and storing instructions.

Firstly, memopt works on the SSA form to combine all locations of an object into one alias.
After that, the optimization updates use-def dependencies with the alias instead of locations.
According to these new dependencies, memopt deletes redundant stores. Finally, it performs
scoped hash-value numbering on the resulting control flow graph to eliminate redundant load
