use raw_ostream instead of std::ostream.  Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).

Other interesting changes:
 1) This makes Value::print be non-virtual.
 2) AP[S]Int and ConstantRange can no longer print to ostream directly, 
    use raw_ostream instead.
 3) This fixes a bug in raw_os_ostream where it didn't flush itself 
    when destroyed.
 4) This adds a new SDNode::print method, instead of only allowing "dump".


A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream 
versions.

This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.

Make sure to create CXX record decls for the implicit Obj-C type declarations. This lets us compile Cocoa.h as Objective-C++

 - 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.

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).

 - 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
