5814008f4b Create a static version of Instruction::getOpcodeName(opCode) that 
can be invoked with only an opcode (i.e., without an instruction).
Move all opCode->opCodeName translations there.

29ab9f8348 Added subclass ConstantExpr to represent expressions consructed from 
constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.   This is why isConstantExpr() is needed.

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!

7a4be9580e Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}. 
An (explicit or implicit) operand may now be both a def and a use.
Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.

71fb71628a Add ability to update existing variables with values read from the command line 
to certain classes.  This is nice because it means that in header files we can
just declare a value, and still have that value be set based on a command-line
argument.  The difference is now that the #include of CommandLine.h does not
need to go into the header file as well.
