Jakob Stoklund Olesen c2ecf3efbf Break false dependencies before partial register updates. 
Two new TargetInstrInfo hooks lets the target tell ExecutionDepsFix
about instructions with partial register updates causing false unwanted
dependencies.

The ExecutionDepsFix pass will break the false dependencies if the
updated register was written in the previoius N instructions.

The small loop added to sse-domains.ll runs twice as fast with
dependency-breaking instructions inserted.
