<rdar://problem/13560075> Teach name lookup for builtin names to find hidden declarations. Normal name lookup ignores any hidden declarations. When name lookup for builtin declarations fails, we just synthesize a new declaration at the point of use. With modules, this could lead to multiple declarations of the same builtin, if one came from a (hidden) submodule that was later made visible. Teach name lookup to always find builtin names, so we don't create these redundant declarations in the first place. llvm-svn: 178711
