cmd/link, cmd/internal/goobj: update constants, regenerate testdata 

The constants in cmd/internal/goobj had gone stale (we had three copies of
these constants, working on reducing that was what got me to noticing this).

Some of the changes to link.hello.darwin.amd64 are the change from absolute
to %rip-relative addressing, a change which happened quite a while ago...

Depends on http://golang.org/cl/9113.

Fixes #10501.
