With frame-pointers, exception handlers should restore RBP

port ocaml/ocaml#11031

Shouldn't we have the equivalent change
(replacing env with ()) in the other file
("ocaml/asmcomp/amd64/emit.mlp")?

@gretay-js could you address Xavier's comment, then this can be merged?

We did it for some of the previous PRs ported from upstream, but I think we don't need it. I am not sure exactly how the ocaml/ directory will be updated from upstream, but if it is a rebase onto 4.14, we don't need to port individual patches, and in fact porting them might make it harder to rebase on 4.14.
