.def file for each library. This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

and separates lexical name lookup from qualified name lookup. In
particular:
* Make DeclContext the central data structure for storing and
looking up declarations within existing declarations, e.g., members
of structs/unions/classes, enumerators in C++0x enums, members of
C++ namespaces, and (later) members of Objective-C
interfaces/implementations. DeclContext uses a lazily-constructed
data structure optimized for fast lookup (array for small contexts,
hash table for larger contexts).
* Implement C++ qualified name lookup in terms of lookup into
DeclContext.
* Implement C++ unqualified name lookup in terms of
qualified+unqualified name lookup (since unqualified lookup is not
purely lexical in C++!)
* Limit the use of the chains of declarations stored in
IdentifierInfo to those names declared lexically.
* Eliminate CXXFieldDecl, collapsing its behavior into
FieldDecl. (FieldDecl is now a ScopedDecl).
* Make RecordDecl into a DeclContext and eliminates its
Members/NumMembers fields (since one can just iterate through the
DeclContext to get the fields).

instead of converting them to strings first. This also fixes a
bunch of minor inconsistencies in the diagnostics emitted by clang
and adds a bunch of FIXME's to DiagnosticKinds.def.

with implicit quotes around them. This has a bunch of follow-on
effects and requires tweaking to a whole lot of code. This causes
a regression in two tests (xfailed) by causing it to emit things like:
Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')
instead of:
Line 10: duplicate interface declaration for category 'MyClass1(Category1)'
I will fix this in a follow-up commit.
As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency. This is good, but I was planning to do this
as an independent patch. There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

from Sebastian to enforce that a literal string is passed in,
and use this to avoid having to call strlen on it.

diagnostics on use of __weak attribute on fields,
Early support for read/write barriers for objc fields.

__builtin_prefetch code to only emit one diagnostic per builtin_prefetch.
While this has nothing to do with the rest of the patch, the code seemed
like overkill when I was updating it.

- Support noreturn on function-typed variables.
- Extend isFunctionOrMethod to return true for K&R functions and
provide hasFunctionProto to check if a decl has information about
its arguments. This code needs some serious cleaning, but works.
- Add/improve test cases for noreturn and unused.

is to encode the state of the #pragma pack stack as an attribute when
the structure is declared.
- Extend PackedAttr to take an alignment (in bits), and reuse for
both __attribute__((packed)) (which takes no argument, instead
packing tightly (to "minimize the memory required") and for #pragma
pack (which allows specification of the maximum alignment in
bytes). __attribute__((packed)) is just encoded as Alignment=1.
This conflates two related but different mechanisms, but it didn't
seem worth another attribute.
- I have attempted to follow the MSVC semantics as opposed to the gcc
ones, since if I understand correctly #pragma pack originated with
MSVC. The semantics are generally equivalent except when the stack
is altered during the definition of a structure; its not clear if
anyone does this in practice. See testcase if curious.

anywhere near correct in terms of missing cases and missing
diagnostics, but it's good enough to handle the uses in the
Linux system headers, which are currently a constant pain for compiling
applications on Linux.

- warn about nonnull being applied to functions with no pointer arguments
- continue processing argument list in the attribute when we encounter a non-pointer parameter being marked as nonnull
- when no argument list is specified, only mark pointers as nonnull. This fixes PR 2732 and radar 6188814.

- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.

- Including possible priority argument
- In other news, the attribute parsing code really needs a cleanup

anyway, so there is no real loss here. Start making attribute processing
methods static functions instead of methods on Sema.

decl attributes out of the various places they can hide. This makes
us correctly reject things like this:
t.c:2:22: error: mode attribute only supported for integer and floating-point types
int **__attribute((mode(HI)))* i32;
^
because you can't make a pointer be HImode.
