Log: MIPS: Refactor HType to get rid of various hacks.
Port r21578 (dcf13aa)
Original commit message:
- Move HType to it's own file.
- Add HType::HeapObject and some other useful types.
- Get rid of the broken and useless HType::NonPrimitive.
- Introduce HType::FromType() to convert from HeapType to HType.
- Also add unit tests for HType.
- Fix types in Crankshaft.
