- Added MRegisterInfo::getCrossCopyRegClass() hook. For register classes where reg to reg copies are not possible, this returns another register class which registers in the specified register class can be copied to (and copy back from).
- X86 copyRegToReg() now supports copying between EFLAGS and GR32 / GR64 registers.
