 - This is easier to use, and more reliable for timing the thing this was
   actually meant to be useful for.

source file has been changed. Handle that failure more gracefully.

This is the way I would like to move the frontend function towards -- distinct
pieces of functionality should be exposed only via FrontendAction
implementations which have clean and relatively-stable APIs.

This also isolates the surface area in clang which depends on LLVM CodeGen.

related to <rdar://problem/6596843> clang ObjC rewriter: Line endings still mixed in rewrite output

This fix was dropped when I integrated the 'objective-rewrite' branch.

Fix CompilerInstance::createOutputFile to use proper diagnostics, and (try to) update all clients to be able to handle failure.

stat a file but where mmaping it fails.  In this case, we emit an
error like:
t.c:1:10: fatal error: error opening file '../../foo.h'

instead of "cannot find file".

this brings the error on
  clang -c foo.h -o -
closer to
  clang -c foo.h -o /dev/null

 - This ended up being hard to factor, sorry for the large diff.

 - Some post-commit cleanup to come.

Add FrontendActions, which provides a FrontendAction interface to all the existing AST consumer based clang-cc actions.
