4900116ab0 Add methods to query about the representation of LLVM quantities (e.g., 
constants).  Useful for target-dependent LLVM transformations like
Preselection.

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!

c864fde15c New function CreateSignExtensionInstructions. 
Methods now take MachineCodeForInstruction& as an argument and record
temporary values in it directly, instead of return the temps.
Really simplifies callers.
