that they are C++0x extensions, and put them in the appropriate
group. We already support most of the semantics. Addresses

Wait, what?
So, we run Clang (and LLVM) tests in an environment where the md5sum of the
input files becomes a component of the path. When testing the preprocessor,
the path becomes part of the output (in line directives). In this test, we
were grepping for the absence of "abc" in the output. When the stars aligned
properly, the md5sum component of the path contained "abc" and the test
failed. Oops.

I've edited one diagnostic which would print "copy constructor" for copy
constructors and "constructor" for any other constructor. If anyone is
extremely enamored with this, it can be reinstated with a simple boolean
flag rather than calling getSpecialMember, which is inappropriate.

the semantic context referenced by the nested-name-specifier rather
than the syntactic form of the nested-name-specifier. The previous
incarnation was based on my complete misunderstanding of C++
[temp.expl.spec]. The latest C++0x working draft clarifies the
requirements here, and this rewrite is intended to follow that.
Along the way, improve source location information in the
diagnostics. For example, if we report that a specific type needs or
doesn't need a 'template<>' header, we dig out that type in the
nested-name-specifier and highlight its range.

Focus is on default constructors for the time being. Currently the
exception specification and prototype are processed correctly. Codegen
might work but in all likelihood doesn't.
Note that due to an error, out-of-line defaulting of member functions is
currently impossible. It will continue to that until I muster up the
courage to admit that I secretly pray to epimetheus and that I need to
rework the way default gets from Parse -> Sema.

hasTrivialDefaultConstructor() really really means it now.
Also implement a fun standards bug regarding aggregates. Doug, if you'd
like, I can un-implement that bug if you think it is truly a defect.
The bug is that non-special-member constructors are never considered
user-provided, so the following is an aggregate:
struct foo {
foo(int);
};
It's kind of bad, but the solution isn't obvious - should
struct foo {
foo (int) = delete;
};
be an aggregate or not?
Lastly, add a missing initialization to FunctionDecl.

also consider whether any of the parameter types (as written, prior to
decay) are dependent. Fixes PR9880 and <rdar://problem/9408413>.

bit by allowing __weak and __strong to be added/dropped as part of
implicit conversions (qualification conversions in C++). A little
history: GCC lets one add/remove/change GC qualifiers just about
anywhere, implicitly. Clang did roughly the same before, but we
recently normalized the semantics of qualifiers across the board to
get a semantics that we could reason about (yay). Unfortunately, this
tightened the screws a bit too much for GC qualifiers, where it's
common to add/remove these qualifiers at will.
Overall, we're still in better shape than we were before: we don't
permit directly changing the GC qualifier (e.g., __weak -> __strong),
so type safety is improved. More importantly, we're internally
consistent in our handling of qualifiers, and the logic that allows
adding/removing GC qualifiers (but not adding/removing address
spaces!) only touches two obvious places.

an embarrassing bug where we give a redefinition error due to an
Objective-C category (<rdar://problem/9388207>).

build a precompiled header. Use this information to eliminate the call
to SourceManager::getLocation() while loading a precompiled preamble,
since SourceManager::getLocation() itself causes unwanted
deserialization.
