[Bug middle-end/63793] -mcmodel=medium in gfortran on x86_64 emits references that are RIP relative (instead of using the GOT)

Jakub, Do you have any insights on where the code generation for darwin would
fork from linux to use %rip rather than @GOTOFF. The darwin linker developer
says for large code (which I assume means both -mcmodel=medium/large), darwin
should be using @GOT rather than %rip. The most obvious places are those using
the conditional HAVE_AS_GOTOFF_IN_DATA which is set to 0 on darwin, but I am
concerned that could be a red herring and we need to look elsewhere in
gcc/config/i386/i386.[c/md].
