f9b332b59d * Keep track of register alignment as well as register size 
* Add comments
* Add a new allocation_order iterator for register classes which targets may
  use to control the register order and available registers based on properties
  of the function being compiled.
* Remove access to FP and SP registers
* Add new callframe setup opcode support
* Eliminate moveImm2Reg method
* Revamp frame offset handling and prolog/epilog code generation

5023bd4a64 cpMem<->Reg functions now support CC registers (int and FP) correctly. 
A scratch register has to be provided when needed to do the copy.
Also, cpMem<->Reg functions now return a vector of machine instructions.

Added several get{Class,Type} functions.

Suggest/Color methods may modify the MachineInstr (and always did),
so don't make that argument const!
