Many diagnostics use `getErrorPlace` or `getErrorLocation` to report a location. In the presence of line table debug information, `getErrorPlace` uses a source file location and ignores the object file location. However, the object file location is sometimes more useful. This patch changes "undefined symbol" and "out of range" diagnostics to report both object/source file locations. Other diagnostics can use similar format if needed. The key idea is to let `InputSectionBase::getLocation` report the object file location and use `getSrcMsg` for source file/line information. `getSrcMsg` doesn't leverage `STT_FILE` information yet, but I think the temporary lack of the functionality is ok. For the ARM "branch and link relocation" diagnostic, I arbitrarily place the source file location at the end of the line. The diagnostic is not very common so its formatting doesn't need to be pretty. Differential Revision: https://reviews.llvm.org/D112518
