Make -fobjc-nonfragile-abi and -fgnu-runtime imply -fblocks (unless -fno-blocks is specified), because this combination of flags defines an Objective-C runtime that includes a blocks runtime.

The implemented algorithm is overly simplistic (just speculate all branches are
taken)- this is work in progress.

* Add default implementations (no-op) for ExternalASTSource's pure virtual functions. There are valid use cases that can live with these defaults.
* Move ExternalASTSource's out of line implementations into separate source file.
* Whitespace, forward decl, #include cleanup.

I've only covered C++'s flags here, we should probably do something
similar for ObjC flags.

ObjC branch, this just mirrors that logic on the C++ side of things.
Thanks to John Wiegley for pointing this out.

- Add appropriate TableGen patterns for fadd, fsub, fmul.
- Add .f32 as the PTX type for the LLVM float type.
- Allow parameters, return values, and global variable declarations
  to accept the float type.
- Add appropriate test cases.

The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

C++ exceptions, even when exceptions have been turned off using -fno-exceptions.
Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions.

C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and
-fno-objc-exceptions.

test case to CodeGen/union.c that would have caught the problem with the
previous attempt. No change in functionality intended.
