Tweak VariadicMethodTypeChecker to only create one ExplodedNode when issuing multiple warnings for the same message expression.

Also add a test case showing that we correctly report multiple warnings for the same message expression.

Add an Objective-C checker that checks that arguments passed to some variadic Objective-C methods are of Objective-C pointer types.

Ted or Argiris, I'd appreciate a review!

Change the interface to expose the new information and deal with the enormous fallout.
Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications.
Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support.

headers, which use C++0x generalized initializer lists. Per PR7069, it
appears that the only use is as the return type of a function, so this
commit enables this extension just in that narrow case. If it's enough
for libstdc++ 4.5, or if it can be trivially extended to work with
libstdc++ 4.5, we'll keep it. Otherwise, or if this breaks anything,
we'll revert and wait for the real feature.

Profiling showed that 'CheckImplicitConversions' was very slow because of the call to getSpellingLoc().  On 'aes.c'
in the LLVM test suite, this function was consuming 7.4% of -fsyntax-only time.  This change fixes this issue
by delaying the check that the warning would be issued within a system macro by as long as possible.  The
main negative of this change is now the logic for this check is done in multiple places in this function instead
of just in one place up front.
