Tidy up sema processing of attribute "nonull":
- 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.

Add Objective-C property setter support.
- Change Obj-C runtime message API, drop the ObjCMessageExpr arg in
favor of just result type and selector. Necessary so it can be
reused in situations where we don't want to cons up an
ObjCMessageExpr.
- Update aggregate binary assignment to know about special property
ref lvalues.
- Add CodeGenFunction::EmitCallArg overload which takes an already
emitted rvalue.
Add CodeGenFunction::StoreComplexIntoAddr.
Disabled logic in Sema for parsing Objective-C dot-syntax that
accesses methods. This code does not search in the correct order and
the AST node has no way of properly representing its results.
Updated StmtDumper to print a bit more information about
ObjCPropertyRefExprs.

Refactor handling of calls:
- Added CodeGenFunction::EmitCall which just takes the callee, return
type, and a list of (Value*,QualType) pairs.
- Added CodeGenFunction::EmitCallArg which handles emitting code for
a call argument and turning it into an appropriate
(Value*,QualType) pair.
- Changed Objective-C runtime interface so that the actual emission
of arguments for message sends is (once again) done in the code to
emit a message send.
No intended functionality change, this is prep work for better ABI
support and for Objective-C property setter support.

Improve ccc:
- Support environment variable CCC_LANGUAGES to control which
languages clang is invoked on. If unset clang is invoked for all
languages, otherwise CCC_LANGUAGES should be a comma separated list
of the languages (as accepted by -x) for which clang should be
invoked. Useful for only building C and Objective-C parts of a
project with clang, for example.
- Add environment variable CCC_FALLBACK. If set and non-empty then
ccc will try and compile using the regular compiler if compilation
with clang fails.
- A few other tweaks to add options, flush stdout, recognize .mm as
objective-c++, and infer languages for compile+link style
invocations.

Add synthesized property methods to protocols and categories in Sema.
- It is not clear that this is the right approach, but this is at
least consistent with how interfaces are handled.
- This means NeXT now emits the correct metadata for properties in
protocols.
- This currently introduces a spurious warning involving inherited
properties in protocols or categories; however, it also fixes some
situations where we were failing to emit a warning. I will scrub
this code tomorrow and fix this issue as well as number of other
missed warnings / error situations that appear to exist.

Objective-C @synthesize support.
- Only supports simple assignment and atomic semantics are ignored.
- Not quite usable yet because the methods do not actually get added

epilog code.

In incompatible pointer-typed ?: expressions, add implicit conversion
of RHSs to id type instead of void* if either has Objective-C object
type.
- This ensures the result can still be used in normal places an
object can be used, like a message send.
Add implicit conversions for ?: applied to qualified id types to
ensure that the RHSs are compatible.
- This prevents a codegen crash (creating invalid PHI nodes).
- Again, this relates to the fact that qualified id types have no
canonical types.
- Note that the implicit type casted to is incorrect, however this
doesn't currently cause problems because of the flexibility of the
id type.

Fix for PR2720; be a little bit more permissive in initializers for

Eventually, we should check whether we can evaluate an expression
