Revert r191586 and r191695. They cause crashes when building with
-relaxed-aliasing.

Fix typo correction usage of SemaAccess.cpp.

When we check access for lookup results, make sure we propagate the
result's access to the access control APIs; this can be different from
the natural access of the declaration depending on the path used by the lookup.

Fix computation of linkage within nested lambdas.

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]
