The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

- 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.

Some assemblers do not recognize aliases pushfd, pushfq, popfd, and popfq. Just emit them as pushf and popf.
