For 'x::template y', consistently give a "no member named 'y' in 'x'" diagnostic if there is no such member, and give a 'template keyword not followed by a template' name error if there is such a member but it's not a template. In the latter case, add a note pointing at the non-template. Don't suggest inserting a 'template' keyword in 'X::Y<' if X is dependent if the lookup of X::Y was actually not a dependent lookup and found only non-templates. llvm-svn: 332076
