This CL enables moving the bulk of the object writing code out of liblink and into translated Go libraries in cmd/internal/obj, but it does not do the move. This CL introduces two new environment variables, $GOOBJ and $GOOBJWRITER, but both will be deleted along with the rest of the liblink C code. The default behavior of a build is unchanged by this CL: the C version of liblink uses the C object layout and writing code. If $GOOBJ=1, liblink invokes go tool objwriter instead. If $GOOBJ=2, liblink does its own layout and then invokes go tool objwriter, which checks that it gets the same answer. That is, in $GOOBJ=2 mode, both the C and the Go version of the code run, and the operation fails if the two produce different answers. This provides a very strong check that the translation is working correctly.
