overflows, including unsigned.  I added some testcases so we don't
break anything.

Also included is another patch from David for += and friends.

- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.

Remove warning from CheckObjCString.

As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).

#ifdef'd out the 5 conversion routines that we don't currently need.

Still need a bit more work in GetAddrOfConstantCFString(). Added a FIXME to indicate this.

Expect to remove the FIXME today...

    1. They fit nicely in a  register.
    2. All fields fit nicely in a register.

Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).
