*** Implement frame pointer elimination on X86! * Include contents of X86RegisterClasses.cpp into here * Adjustments to register api to work with new frame manager * Eliminate moveImm2Reg, getFramePointer, and getStackPointer * Cleanup and simplify prolog/epilog code generation * Prolog/epilog are MUCH more efficient now.
