libstdc++: Fixes for tests that fail with -fno-rtti

This disables a use of dynamic_cast that is not valid for -fno-rtti and
adjusts some tests so they don't FAIL with -fno-rtti. Some tests are
skipped completely, and others just make use of typeid conditional on
the __cpp_rtti macro. A couple of tests were using typeid to verify
typedefs denote the right type, which can be done at compile-time using
templates instead.
