spyffe created this revision.
When parsing types originating in modules, it is possible to encounter
`AttributedType`s (such as the type generated for `NSString *_Nonnull`). Some
of LLDB's `ClangASTContext` methods deal with them; others do not. In
particular, one function that did not was `GetTypeInfo`, causing
`TestObjCNewSyntax` to fail.
This fixes that, treating `AttributedType` as essentially transparent and
getting the information for the modified type.
In addition, however, `TestObjCNewSyntax` is a monolithic test that verifies a
bunch of different things, all of which can break independently of one another.
I broke it apart into smaller tests so that we get more precise failures when
something (like this) breaks.
