hierarchy of delegation, and that EH selector values are meaningful function-wide (good thing, too, or inlining wouldn't work). 2,3d 1a hierarchy of delegation and that EH selector values have the same meaning everywhere in the function instead of being meaningful only in the context of a specific selector. This removes the need for routing edges through EH cleanups, since a cleanup simply always branches to its enclosing scope. llvm-svn: 137293
