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
to the class metadata.
- Added ObjCPropertyDecl::getSetterKind (one of Assign, Copy, Retain).
- Rearrange CodeGenFunction so synthesis can reuse function prolog /
epilog code.

Synthesize property setter method as we do for getter.
- Also, fix Parser to construct proper SetterName selector (should be
lifted out of parser though).

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.

Do typechecking and codegen for K&R-style function declarations

Fix for PR2720; be a little bit more permissive in initializers for
casting pointers to integers.
Eventually, we should check whether we can evaluate an expression
using Expr::tryEvaluate, and this codepath should be tightened to only
handle standard-compliant cases.

Add CodeGenFunction::EmitUnsupportedLValue
- Gives error and returns undef value.
Swap some asserts() over to using EmitUnsupportedLValue
- Rumor has it users (and even some developers) prefer carat
diagnostics to backtraces.
- Works better in Release-Asserts to boot.

Do is-a-pointer checks in terms of LLVM types in

that id is effectively a pointer type.

Update ccc driver
- Use CCC_ECHO to control echoing behavior (default is on, set to ''
or unset to disable)
- Get 'clang','llc','as','cc','ld' executables from environment. 'cc'
and 'ld' are fetched through CCC_CC and CCC_LD respectively -- to
support make CC=ccc -- the others are through their upcased
versions.
- Add CCC_NATIVE mode.
o This uses llc and as to generate native object files; allowing
more drop-in replacement of gcc.
o Disabled by default, but should eventually be default.
o Allow --emit-llvm in CCC_NATIVE mode to override. Essentially
this makes ccc more like a drop in replacement for llvm-gcc.
- Prevent explicit -x <language> options from annoying clang.
Update several places to emit more precise ErrorUnsupported warnings
for currently unimplemented Obj-C features (main missing chunks are
property references, Obj-C exception handling, and the for ... in
syntax).

- Reduced to only taking the CodeGenFunction, Expr, and Receiver.
- Becomes responsible for emitting the arguments.
Add CodeGenFunction::EmitCallExprExt
- Takes optional extra arguments to insert at the head of the call.
- This allows the Obj-C runtimes to call into this and isolates the
argument and call instruction generation code to one place. Upshot
is that we now pass structures (more) correctly.
Also, fix one aspect of generating methods which take structure
arguments (for NeXT). This probably needs to be merged with the
SetFunctionAttributes code in CodeGenModule.cpp

Add support for C++'s "type-specifier ( expression-list )" expression:
-The Parser calls a new "ActOnCXXTypeConstructExpr" action.
-Sema, depending on the type and expressions number:
-If the type is a class, it will treat it as a class constructor. [TODO]
-If there's only one expression (i.e. "int(0.5)" ), creates a new "CXXFunctionalCastExpr" Expr node
-If there are no expressions (i.e "int()" ), creates a new "CXXZeroInitValueExpr" Expr node.
