Teach the module import mechanism how to rebuild modules expressed via
module map, rather than assuming that there is an umbrella

Remove the last of my notes. I don't think these really need to be in
the release notes despite their awesomeness. If we had a thorough
discussion of the performance of Clang in 2.9 vs. 3.0, the first would
be more relevant, but we don't. The serialization stuff hopefully isn't
terribly visible to end users.
Objections to these omissions are of course welcome. =]

The _setjmp builtin library function should have the "returns twice"

Constructors/destructors are handled by the CFG, but we do not do anything

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.
