The _setjmp builtin library function should have the "returns twice"
attribute. This prevents the stack slot allocator from coming along and using a
stack which it thinks is available but isn't.

Correct the code generation for function arguments of vec3 types on x86_64 when they are greater than 128 bits. This was incorrectly coercing things like long3 into a double2.

When attempting to load a module that is not in the module cache,
return the module itself (in the module map) rather than returning the
umbrella header used to build the module. While doing this, make sure
that we're inferring modules for frameworks to build that module.

Cleanup the Release Notes for the static analyzer:
The performance improvement was committed after the 3.0 branch.
Constructors/destructors are handled by the CFG, but we do not do anything
special for them in the analyzer yet.
Since we do not have an open source release qualification for the analyzer,
we are not investing into creating the proper release notes for it.

And that completes my sweep through commits for things that might be
worth noting in the release notes. These remain raw notes. I'll be
re-writing them into nice prose first thing tomorrow, with help from
others. A couple of notes for any reading the commits:
If you don't see something that should be mentioned, feel free to add
a note (or even a nicely written section) about it! I haven't really
done the static analyzer justice here as I don't really know what the
significant changes are other than mile-high stuff like watching it grow
C++ support and a more robust CFG. I also worry I've missed important
stuff in the Objective-C world.
If you see something that isn't worth mentioning, just delete it. I know
there are several things like this. I plan to prune the list down as
I flesh things out.
If you're name or email is on a bullet, I'll likely be sending you an
email asking for any input on that subject. For many of these I can fill
in something generic, and I'll just want you to give it a once-over.
However, if you have time, feel free to just write the blurb yourself
and drop it in, or drop it in an email to me.
Finally, *WOW* has a lot happened in Clang... I shouldn't have dreaded
(and put off) this so much, it was kind of awesome to go back and watch
the evolution. Anyways, these should be in a reasonable draft state
early tomorrow.

Begin sketching out the Clang release notes. The plan is to link to
these more detailed notes from the primary LLVM release notes for Clang.
This gives us a nice place to flesh out in plenty of detail the major
changes that have happened in Clang land since 2.9.
I've outlined a very rough structure based on the LLVM release notes
structure and what seems like useful divisions in the Clang landscape
(e.g., language-specific stuff is relevant to a narrower audience).
I'll be first converting my brain-dump-ish notes from the commit logs,
and then cleaning here. Suggestions on structure welcome. Typo
corrections, spelling fixes (oh how I'll need them), all welcome; just
commit away.
When destroying temporaries, instead of a custom cleanup use the
generic pushDestroy function.
This would reduce the number of useful declarations in
CGTemporaries.cpp to one. Since CodeGenFunction::EmitCXXTemporary
does not deserve its own file, move it to CGCleanup.cpp and delete
CGTemporaries.cpp.

In Microsoft mode, make "Unqualified lookup into dependent bases of class templates" works inside a friend function definition at class scope.
Basically we have to look into the parent *lexical* DeclContext for friend functions at class scope. That's because calling GetParent() return the namespace or file DeclContext.
This fixes all remaining cases of "Unqualified lookup into dependent bases of class templates" when parsing MFC code with clang.

Add feature to diagnostics that will provide more information on function

qualifier mismatch.
[libclang] Fix operations (token annotation, getting cursor, etc.) with a file region
inside an objc container that "contains" other file-level declarations.
When getting the array of file-level declarations that overlap with a file region,
we failed to report that the region overlaps with an objc container, if
the container had other file-level declarations declared lexically inside it.
Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST
and handling them appropriately.

Add driver arguments -ftemplate-depth=N and -fconstexpr-depth=N, with the same
semantics and defaults as the corresponding g++ arguments. The historical g++
argument -ftemplate-depth-N is kept for compatibility, but modern g++ versions
no longer document that option.
Add -cc1 argument -fconstexpr-depth N to implement the corresponding

Teach the driver about failure result files, which are compilation
output files that are valid regardless of whether the compilation
succeeded or failed (but not if we crash). Add depfiles to the
failure result file list.
