The current hacked together location API we added to drgn works extremely poorly with modern C++ compilers. It largely works with the clang-12 compiler on CircleCI, but works very poorly with clang 15/16/17/18 in Nix or when updating the CircleCI compiler to clang-15. This change adds a backup mechanism for locating arguments when drgn has failed. The mechanism is extremely naive and makes several assumptions which are often not correct. Currently, however, it drastically reduces the number of tests that must be skipped in the Nix CI. Test plan: - CI
