Refactor the memcpy lowering for the x86 target.

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.

TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targets

other than PPC64. Instead of fixing it, just remove it and fix all the

aren't very many. Most of the references were in DwarfWriter.cpp.
