Redeclaration checking was validating all declarations with the same base name as the given declaration (and in the same general nominal type), even when it was trivial to determine that the declarations could not be conflicting. Separate out the easy structural checks (based on kind, full name, instance vs. non-instance member, etc.) and perform those first, before validation. Fixes SR-6558, a case where redeclaration checking caused some unnecessary recursion in the type checker.
