[RFC](https://discourse.llvm.org/t/rfc-add-build-id-flag-to-lld-link/74661) Before, lld-link only generate the debug directory containing guid when generating PDB with the hash of PDB content. With this change, lld-link can generate the debug directory when only `/build-id` is given: 1. If generating PDB, `/build-id` is ignored. Same behaviour as before. 2. Not generating PDB, using hash of the binary. - Not under MinGW, the debug directory is still in `.rdata` section. - Under MinGW, place the debug directory into new `.buildid` section.
