[PATCH] [LSR] Generate and use zero extends

[Sanjoy Das]

address review:

- change Formula::print to indicate that a specific formula is a zext formula
- add comment on LSRInstance::GenerateZExts
- the existing test case tests both pre-inc and post-inc uses (commented).  Please let me know if this is not what you meant.
