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.

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

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;

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.

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.

 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]

Before, this could would lead to an assert:

The general strategy is to create template versions of the conversion function and static invoker and then during template argument deduction of the conversion function, create the corresponding call-operator and static invoker specializations, and when the conversion function is marked referenced generate the body of the conversion function using the corresponding static-invoker specialization.  Similarly, Codegen does something similar - when asked to emit the IR for a specialized static invoker of a generic lambda, it forwards emission to the corresponding call operator. 

This patch has been reviewed in person both by Doug and Richard.  Richard gave me the LGTM.

A few minor changes:
  - per Richard's request i added a simple check to gracefully inform that captures (init, explicit or default) have not been added to generic lambdas just yet (instead of the assertion violation).
  - I removed a few lines of code that added the call operators instantiated parameters to the currentinstantiationscope. Not only did it not handle parameter packs, but it is more relevant in the patch for nested lambdas which will follow this one, and fix that problem more comprehensively.
  - Doug had commented that the original implementation strategy of using the TypeSourceInfo of the call operator to create the static-invoker was flawed and allowed const as a member qualifier to creep into the type of the static-invoker.  I currently kludge around it - but after my initial discussion with Doug, with a follow up session with Richard, I have added a FIXME so that a more elegant solution that involves the use of TrivialTypeSourceInfo call followed by the correct wiring of the template parameters to the functionprototypeloc is forthcoming.

Thanks!

Clang uses UTF-16 and UTF-32 for its char16_t's and char32_t's
exclusively. This means that we can define __STDC_UTF_16__ and
__STDC_UTF_32__ unconditionally.

While there, define __STDC_MB_MIGHT_NEQ_WC__ for FreeBSD. FreeBSD's
wchar_t's don't encode characters as ISO-10646; the encoding depends on
the locale used. Because the character set used might not be a superset
of ASCII, we must define __STDC_MB_MIGHT_NEQ_WC__.

- We scan for whitespace between comments anyways, remember any newlines seen
  along the way.
- Use this newline number to decide whether two comments are adjacent.
- Since the newline check is now free remove the caching and unused code.
- Remove unnecessary boolean state from the comment list.
- No behavioral change.

findMultiLibSuffix(). This function called during GCC installation

language wording and avoids some cases where code gets confused by them for
namespace-scope lambdas and the like.

...rather than trying to figure it out from the call site, and having
people complain that we guessed wrong and that a prototype-less call is
the same as a variadic call on their system. More importantly, fix a
crash when there's no decl at the call site (though we could have just
returned a default value).
