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).

 - Simplify the sending code a bit.

 - 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.

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

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

because nothing uses the merged types yet.)

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.

 - Functional for simple cases but there are some glaring omissions
   (protocols, properties, and other language extensions).
 - The code needs a fair bit of cleaning.

difference from generic x86 is the defines.  The rest is non-trivial to 
implement.

I'm not planning on adding any more targets myself; if there are any 
targets anyone is currently using that are missing, feel free to add 
them, or ask me to add them.

This concludes the work I'm planning for the TargetInfo 
implementations at the moment; all the other issues with TargetInfo require
some API changes, and I haven't really thought it through.  Some of the
remaining issues: allowing targets to define size_t and wchar_t properly,
adding some sort of __builtin_type_info intrinsic so we can finish clang's 
limits.h and float.h and get rid of a massive number of macro 
definitions, allowing target-specific command-line options, allowing
target-specific defaults for certain command-line options like
-fms-extensions, exposing vector alignment outside of the description 
string, exposing endianness outside of the description string, allowing 
targets to expose special bit-field layout requirements, exposing some 
sort of custom hook for call generation in CodeGen, and adding CPU 
selection to control defines like __SSE__.

This approach allows adding OS-specific targets/defines/etc. without 
completely breaking unknown subtargets.  No new subtargets yet, although 
I plan to add x86-Linux soon.  Others can add targets that they use as 
needed; adding a new subtarget takes very little code.

Also does some fixups for description strings; a lot of them were 
unspecified.  I think all the ones I added are correct, but 
they're unverified; corrections are welcome.

up somehow.

This concludes the series of reorg patches for the target 
implementations.
