This revision splits the medium/large code model toc reference after
reload. I expected this to be more difficult, but it turned out
surprisingly easy. Besides creating the rtl that way, and tweaking
toc_relative_expr_p to match, it was just: Move the 'R' constraint
handling out of various movsi

No, nothing as complicated as that. In a lot of cases, any hoisting
of the high part is bad, because the linker nops out the high part and
