Reviewed by Geoff Garen.

Port more of the JIT to use the MacroAssembler interface.

Everything in the main pass, bar a few corner cases (operations with required
registers, or calling convention code). Slightly refactors array creation,
moving the offset calculation into the callFrame into C code (reducing code
planted).

Overall this appears to be a 1% win on v8-tests, due to the smaller immediates
being planted (in jfalse in particular).
