[Chris Lattner]

Changes in directory llvm/include/llvm/Target:

MRegisterInfo.h updated: 1.8 -> 1.9

---
Log message:

* Rename const_regclass_begin/end to just regclass_begin/end
* Regclass iterators need an extra level of pointerness to work right
* Pull inverse mapping code out of target description files
