[PATCH] D69760: [Clang][Driver] Don't pun -fuse-ld=lld as -fuse-ld=lld-link with msvc

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

> I think a better distinguisher would be whether clang was invoked as clang[++] or clang-cl (i.e. driver mode).

I think Martin said most of what I wanted to say. Making this dependent on the driver mode seems reasonable and would be the easier way forward.

If you still want to make `clang-cl -fuse-ld=lld` call `ld.lld` with gnu-style flags, you will need to pre-fix the various in-tree test suites. If you look through the LLDB, compiler-rt, and debuginfo-tests test suites, you will see many instances of `-fuse-ld=lld` that rely on the current behavior. See cases like:
https://github.com/llvm/llvm-project/blob/dd0c00b5f8b303f78565ab407d37a643e99a9e75/compiler-rt/test/asan/lit.cfg.py#L96
Maybe that case in particular doesn't apply, but it needs to be looked into.
