[PATCH] D45467: [wip] COFF: Friendlier undefined symbol errors.

[Peter Collingbourne via Phabricator via llvm-commits]

pcc created this revision.
pcc added reviewers: zturner, ruiu.
Herald added subscribers: JDevlieghere, aprantl.

This change does three things:

- Try to find the file and line number information of an undefined symbol reference by reading codeview debug info.
- Try to find the name of the function or global variable with the undefined symbol reference by searching the object file's symbol table.
- Prints the information in the same style as the ELF linker.

TODO: Update tests.
