When nested lambdas are used in NSDMI's - this prevents infinite recursion. See http://llvm-reviews.chandlerc.com/D1783 for Doug's approval regarding the code, and then request for some tests. [On a related note, I need this patch so as to pass tests of transformations of nested lambdas returned from member functions] llvm-svn: 191645
