Seems this complicated lldb sufficiently for some cases that it hasn't been worth supporting/fixing there - and it so far hasn't provided any new use cases/value for debug info consumers, so let's remove it until someone has a use case for it. (side note: the original implementation of this still had a bug (I should've caught it in review) that we still didn't produce auto-returning function declarations in types where the function wasn't instantiatied (that requires a fix to remove the `if getContainedAutoType` condition in `CGDebugInfo::CollectCXXMemberFunctions` - without that, auto returning functions were still being handled the same as member function templates and special member functions - never added to the member list, only attached to the type via the declaration chain from the definition) Further discussion about this in D123319 This reverts commit5ff992bca2: [DEBUG-INFO] Change how we handle auto return types for lambda operator() to be consistent with gcc This reverts commitc83602fdf5: [DWARF5][clang]: Added support for DebugInfo generation for auto return type for C++ member functions.
