This adds support for the tls_model attribute. This allows the user to
choose a TLS model that is better than what LLVM would select by
default. For example, a variable might be declared as:

  __thread int x __attribute__((tls_model("initial-exec")));

if it will not be used in a shared library that is dlopen'ed.

This depends on LLVM r159077.

attributes in more places where we didn't and catching a lot more issues.

This implements nearly every aspect of C++11 attribute parsing, except for:
 - Attributes are permitted on explicit instantiations inside the declarator
   (but not preceding the decl-spec)
 - Attributes are permitted on friend declarations of functions.
 - Multiple instances of the same attribute in an attribute-list (e.g.
   [[noreturn, noreturn]], not [[noreturn]] [[noreturn]] which is conforming)
   are allowed.
The first two are marked as expected-FIXME in the test file and the latter
is probably a defect and is currently untested.

Thanks to Richard Smith for providing the lion's share of the testcases.

Heavily based on a patch from
Aaron Wishnick <aaron.s.wishnick@gmail.com>.

I'll clean up the duplicated function in CodeGen as
a follow-up, later today or tomorrow.

We don't handle exceptions yet, so we treat them as sinks. ExprEngine
hardcodes messages that are known to raise Objective-C exceptions like -raise,
but it was only checking for +raise:format: and +raise:format:arguments: on
NSException itself, not subclasses.

more consistent.

* Primarily fixed \param commands with names not matching any actual
  parameters of the documented functions.  In many cases this consists
  just of fixing up the parameter name in the \param to match the code,
  in some it means deleting obsolete documentation and occasionally it
  means documenting the parameter that has replaced the older one that
  was documented, which sometimes means some simple reverse-engineering
  of the docs from the implementation;
* Fixed \param ParamName [out] to the correct format with [out] before
  the parameter name;
* Fixed some \brief summaries.

llvm-svn: 158980

* Add \brief summaries;
* Escape # characters in Doxygen comments;

Handle include directive with comments.  It turns out that in this case comments are not coming in source order.  Instead of trying to std::sort() comments (which can be costly), just remove comments that are not in order.

1. Accept flags -g[0-3], -ggdb[0-3], -gdwarf-[2-4] and collapse them to simple -g (except -g0/-ggdb0).
2. Produce driver error on unsupported formats (-gcoff, -gstabs, -gvms) and options (-gtoggle).
3. Recognize and ignore flags -g[no-]strict-dwarf, -g[no-]record-gcc-switches.

In C, enum constants have the type of the enum's underlying integer type,
rather than the type of the enum. (This is not true in C++.) This leads to
odd warnings when returning enum constants directly in blocks with inferred
return types. The easiest way out of this is to pretend that, like C++, enum
constants have enum type when being returned from a block.
