Two issues caused compiler crashes when iterating over containers of FRTs: - The subscript setter and iterator pointee setter assumed operator[] and operator*() return UnsafeMutablePointer<T>, but FRT collapses T& to bare T (a class type), leading to an invalid setter body that crashes during SIL verification. - Containers with raw pointer begin()/end() returning FRT* had the similarly stripped to FRT?, which triggered a downstream conformance check failure for UnsafeCxxInputIterator. This patch bails out of the setter synthesis and conformance derivation when this happens, and adds tests for both std::vector<FRT*> and std::vector<FRT>, as well as a custom container with begin() and end() return FRT *. Known issue: using both vector<FRT> and vector<FRT*> for the same FRT in one compilation unit crashes due to a separate bug where the conformance checker creates duplicate CxxSequence conformances. rdar://180479293
