Make it apply to x86-64 medium and large code models since that's what the backend does. Limit logic to exclude x86-32. Default to 0, let the driver set it to 65536 for the medium code model if one is not passed. Set it to 0 for the large code model by default to match gcc and since some users make assumptions about the large code model that any small data will break.
