Set default version for OpenCL C to 1.2. This means that the
absence of any standard flag will be equivalent to passing
'-cl-std=CL1.2'.
Note that this patch also fixes incorrect version check for
the pointer to pointer kernel arguments diagnostic and
atomic test.

When '__cl_clang_function_pointers' extension is enabled
the parser should allow obtaining the function address.
This fixes PR49264!
Differential Revision: https://reviews.llvm.org/D97203
With the internal clang extension '__cl_clang_variadic_functions'
variadic functions are accepted by the frontend.
This is not a fully supported vendor/Khronos extension
as it can only be used on targets with variadic prototype
support or in metaprogramming to represent functions with
generic prototype without calling such functions in the
kernel code.

The new clang internal extension '__cl_clang_function_pointers'
allows use of function pointers and other features that have
the same functionality:
- Use of member function pointers;
- Unrestricted use of references to functions;
- Virtual member functions.
This not a vendor extension and therefore it doesn't require any
special target support. Exposing this functionality fully
will require vendor or Khronos extension.

Treat 'f()' as 'f(void)' rather than a function w/o a prototype.

Re-apply revision 306653.
llvm-svn: 315453
OpenCL disallows using variadic arguments (s6.9.e and s6.12.5 OpenCL v2.0)
apart from some exceptions:
- printf
- enqueue_kernel
This change adds error diagnostic for variadic functions but accepts printf
and any compiler internal function (which should cover __enqueue_kernel_XXX cases).
It also unifies diagnostic with block prototype and adds missing uncaught cases for blocks.
