New Revision: 300087

URL: http://llvm.org/viewvc/llvm-project?rev=300087&view=rev
Log:
Accept not only lld-link but also LLD-LINK, for example.

Filenames are case-insensitive on Windows, so when we dispatch based
on argv0, we need to handle it case-insensitively.

Fixes https://bugs.llvm.org/show_bug.cgi?id=32637.
