instead of using name and decl context. The advantages of this approach are three-fold: - This is necessary to support inlined generic functions. - We can retire the debugger-specific type name manfgling mode for archetypes. - This saves 270kb of debug information in the x86_64 libSwiftCore.dylib alone. <rdar://problem/38306256>
