There was an assumpiton that TUs and CUs share .debug_str_offsets contribution. For ThinLTO builds it is not the case. Changed so that we parse contributions for TUs also, and did some refactoring so that we don't re-parse contributions that were not modified.

Unrelated: this should be an error, not an assertion.
