 - This is pretty ugly, but the most obvious solution. Chime in if you
   have a nicer one.

 - The problem is that with -save-temps, clang-cc has no idea what the
   name of the original input file is. However, the user expects to be
   able to set breakpoints based on the input file name.

 - We support this by providing a new option -main-file-name (similar
   to -dumpbase used by gcc) which allows the driver to pass in the
   original file name.

 - <rdar://problem/6753383> building with clang using --save-temps
   gets the compile unit name from the .i file...

Add a destination type argument to EmitConstantExpr. This will be used for when the destination has a reference type. (No functionality change yet)

Pointer width on targets like PIC16 is 16-bit, while the valid index size to GEP is only 32 or 64. So promote index to 32 in such cases.

 - Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

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

- 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).
