466df539 - [Runtime] Correctly match demangle tree for generic Objective-C classes.

[Runtime] Correctly match demangle tree for generic Objective-C classes. When we encounter the demangle tree for a bound generic class type, look through the "Type" node of the child tree before checking whether we have an Objective-C class name. If we do have an Objective-C class name, there is no way to preserve the generic arguments, so we ignore them and return the (non-generic) class type. Fixes rdar://problem/47028102.
