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.

Migrated CFRefCount.cpp to use getBindings and BindingsAsString instead of
making assumptions about the Store (removed dependence on GRState::vb_iterator).

Make store "Regions" and "Bindings" more abstract instead of concrete variants.
Their precise semantics will be implemented by a specific StoreManager.
Use function pointer to create the StoreManager in GRStateManager. This matches how we create ConstraintsManager.

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
