On case-insensitive file systems, the editor may send us a path that works but doesn't match the actual file's case. Then when we run go list, we'll get mismatching paths and everything will break. We can't reliably fix this problem: tracking what case the editor expects is too difficult to be worth it. Instead, check the workspace path and bail if it's mismatched. Possibly we should also check files on DidOpen or such, but we can start with this. Updates golang/go#36904.
