            Bug ID: 31974
           Summary: lld-link fails with "LLVM ERROR: Associative COMDAT
                    symbol 'baz' does not exist." when using LTO
           Product: lld

Reproducer for "Associative COMDAT symbol does not exist."

I tried to build LLVM on Windows with LTO. The tests (anything using
googletest) fail to link, giving "LLVM ERROR: Associative COMDAT symbol 'baz'
does not exist.", where 'baz' is the name of a COMDAT. I've reduced the code
that reproduces the problem to the attached test case.
