Compile-time tuning: register/bb utilities
This CL yeilds about a 4% improvement in the compilation phase
of dex2oat (single-threaded; multi-threaded compilation is
more difficult to accurately measure). The register utilities
could stand to be completely rewritten, but this gets most of the
easy benefit.
Next up: the assembly phase.
