Add a -rewrite-includes option, which is similar to -rewrite-macros, but only expands #include directives.

In standard C since C89, a 'translation-unit' is syntactically defined to have
at least one "external-declaration", which is either a decl or a function
definition. In Clang the latter gives us a declaration as well.

The tricky bit about this warning is that our predefines can contain external
declarations (__builtin_va_list and the 128-bit integer types). Therefore our
AST parser now makes sure we have at least one declaration that doesn't come
from the predefines buffer.

Also, remove bogus warning about empty source files. This doesn't catch source
files that only contain comments, and never fired anyway because of our
predefines.

Zap the /Za compiler switch from MSVC projects, the option is considered harmful even by Microsoft people and clang won't build using the MSVC 2012 RC if not removed.

Within the guts of CheckFormatHandler, the IsObjCLiteral flag was being used in
two ways: to see if null bytes were allowed, and to see if the '%@' specifier
is allowed.* The former usage has been changed to an explicit test and the
latter pushed down to CheckPrintfHandler and renamed ObjCContext, since it
applies to CFStrings as well.

* This also changes how wide chars are interpreted; in OS X Foundation, the
wide character type is 'unichar', a typedef for short, rather than wchar_t.

temporary or an array subobject of a class temporary, and the resulting value
is used to initialize a pointer which outlives the temporary. Such a pointer
is always left dangling after the initialization completes and the array's
lifetime ends.

In order to detect this situation, this change also adds an
LValueClassification of LV_ArrayTemporary for temporaries of array type which
aren't subobjects of class temporaries. These occur in C++11 T{...} and GNU C++
(T){...} expressions, when T is an array type. Previously we treated the former
as a generic prvalue and the latter as a class temporary.

pointer type. Fixes PR12854 and the major part of PR11093.
