Fix computation of linkage within nested lambdas.
 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]

Remove an unnecessary overload from ASTLambda.h 
As Richard pointed out to me, dyn_cast is very cheap - there is no real benefit from adding cluttery overloads to only avoid that cast.
No functionality change.

Add a bunch of other GCC '-f' options and ignore them. This covers every
such option I've been able to find in the wild in our build system.

Note that I haven't added test cases for this. I can do so if folks
want, but they're *really* boring considering that this is all generated
code to parse and ignore unsued options.

clang-format: Improve alignment after 'return'.

Previously, comments, could totally confuse it.

Before:
  return
             // true if code is one of a or b.
             code == a ||
         code == b;

After:
  return
      // true if code is one of a or b.
      code == a || code == b;

Fix use-after-free.

TemplateDeclInstantiator takes the MultiLevelArgumentList by const-ref
and stores a const-ref member. Thus, we must not pass a temporary
into the constructor.

Moving style option formatting to libFormat

The help text for clang-format's -style option and the function that processes
its value is moved to libFormat in this patch. The goal is to enable other
tools that use libFormat and also have a -style option to behave consistently
with clang-format.

Tweak changes in r186464 to avoid a crash.

Currently, IR generation can't handle file-scope compound literals with
non-constant initializers in C++.

Fixes PR17415 (the first crash in the bug).

(We should probably change (T){1,2,3} to use the same codepath as T{1,2,3} in
C++ eventually, given that the semantics of the latter are actually defined by
the standard.)

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]
