meaningful to odr-use the VarDecl inside a variable template. (Separately, it'd be nice to track referenced-ness for templates, and warn on unused ones, but that's really a distinct issue...) Move a test that generates and tests a warning-suppressing error out to its own test file, so it doesn't have weird effects on the other tests in the same file. llvm-svn: 205448
