…ypeAtIndex() This patch introduces a new class SwiftRuntimeTypeVisitor that exists to unify iteration over runtime type information. The visitor callback has closure parameters that can be called to make additional expensive queries on a child. TODO: This is not the final evolution step. - We probably should remove the "depth" parameter entirely and implement the access path computation for GetIndexOfChildMemberWithName at a different layer. - We could cache the results for the last execution context. Relanding with an off-by-one error fixed in GetExistentialSyntheticChildren that was caught by ASAN!
