CodePointerSize and CalleeSaveStackSlotSize values are used in DWARF
generation. In case of MIPS it's incorrect to check for Triple::isMIPS64()
only this function returns true for N32 ABI too.
Now we do not have a method to recognize N32 if it's specified by a command
line option and is not a part of a target triple. So we check for
Triple::GNUABIN32 only. It's better than nothing.
