When nested C++11 lambdas are used in NSDMI's - this patch prevents infinite recursion by computing the linkage of any nested lambda by determining the linkage of the outermost enclosing lambda (which might inherit its linkage from its parent). See http://llvm-reviews.chandlerc.com/D1783 for Doug's approval. [On a related note, I need this patch so as to pass tests of transformations of nested lambdas returned from member functions] llvm-svn: 191727
