Per review feedback the name was wrong and it can be used outside Objective-C. Unfortunately, making the internal struct visible broke some ASTMatchers tests that assumed that the first record decl would be from user code, rather than a builtin type. I'm worried that this will also affect users' code. So this patch adds a typedef to wrap the internal struct and only makes the typedef visible to namelookup. This is sufficient to allow the ASTReader to merge the decls we need without making the struct itself visible. rdar://problem/24425801 llvm-svn: 259734
