Ports:

- core feature: https://reviews.llvm.org/D67039
- case mismatch: https://reviews.llvm.org/D70506
- extern "C" suggestions: https://reviews.llvm.org/D69592, https://reviews.llvm.org/D69650

Does not port https://reviews.llvm.org/D71735 since I believe that that doesn't
apply to lld/Mach-O.

I was a bit skeptical of the feature when it was initially added, but I think it's
proved itself in the ELF port.
