Implement Obj-C lvalue message sends (aggregate returns).

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).

llvm-svn: 55234

 - Simplify the sending code a bit.

llvm-svn: 55232

 - Used to autoselect runtime when neither -fnext-runtime nor
   -fgnu-runtime is specified.
 - Default impl is false, all darwin targets set it to true.

 - Returns an RValue.
 - 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

-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.

make test fails if llvm is checked out to llvm-svn of if there is a dash somewhere else in the path. fix that.

For example, adding the default system include paths in clients is now as
simple as

  InitHeaderSearch init(headers);
  init.AddDefaultSystemIncludePaths(langopts);
  init.Realize();

testing compatibility.  This is necessary for some constructs, like merging
redeclarations.

Also, there are some ObjC changes to make sure that 
typesAreCompatible(a,b) == typesAreCompatible(b,a).  I don't have any 
ObjC code beyond the testsuite, so please tell me if there are any cases 
where this doesn't behave as expected.

implement some things, like unary operators and casts, but it's enough
to fix PR2703 as filed.
