Also get rid of explicitly specified '-march' values for old architectures. This simplifies %ptxas-verify statements. After the change, we can potentially miss cases where a new functionality is added to the architecture without appropriate checks in the backend. On the other hand, this is mostly true for old architectures that have been thoroughly tested. Differential Revision: https://reviews.llvm.org/D141736
