Don't break up lwl/lwr/swl/swr instructions into components when using the interpreter, it can handle the original instructions faster directly.
Remove an unnecessary mask operation when using ins some ways.
Optimize away redundant store+load vector operations (seen a lot in the Wipeout games).
None of these alone have a big effect, but if we keep shaving the size of the generated IR code down, performance will improve. Plus, these are fun to work on and some of this will also benefit the IR Jits.
