Don't depend on dynamic relocatinos in ro sections. Currently we don't check when creating relative relocations if the section is read only or not. I am about to fix that, so first update the patches that depend on the current behavior. llvm-svn: 268542

Don't depend on lld creating relocations in ro segments. We currently don't do a good job of diagnosing inputs that would require dynamic relocations to be applied to read only segments. I am about to improve lld in that area, but unfortunately we developed tests that depend on the current behavior. To make clear what is actually changing, this first patch just updates tests to not depend on the current behavior. In most cases this just means using a rw section instead of a ro one, but that unfortunately changes many addresses. llvm-svn: 268145
