Vikram S. Adve 4e537b27d8 Added subclass ConstantExpr to represent expressions consructed from

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.

Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it

Vikram S. Adve aee6701e63 Significant changes to correctly spill CC registers and to correctly 
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
   Also, cpMem<->Reg functions now return a vector of machine instructions.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
   needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
   since regs used to save values *across* an instruction are not obvious
   either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
   This is needed for conditional move operations.
   So an operand may need spill code both before and after the instruction.

Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
   so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
   handling CC registers since cpMem<->Reg handle those correctly now.
