In C++ mode we should only avoid adding __OPENCL_C_VERSION__,
all other predefined macros about the language mode are still
valid.
This change also fixes the language version check in the
headers accordingly.

Defining CLK_NULL_EVENT with a `(void*)` cast has the (unintended?)
side-effect that the address space will be fixed (as generic in OpenCL
2.0 mode). The consequence is that any target specific address space
for the clk_event_t type will not be applied.
It is not clear why the void pointer cast was needed in the first
place, and it seems we can do without it.

We accidentally lost the ATOMIC_VAR_INIT and ATOMIC_FLAG_INIT macros
in r363794.
Also put the `memory_order` typedef back inside a `>= CL2.0` guard.

Using the -fdeclare-opencl-builtins option will require a way to
predefine types and macros such as `int4`, `CLK_GLOBAL_MEM_FENCE`,
etc. Move these out of opencl-c.h into opencl-c-base.h such that the
latter can be shared by -fdeclare-opencl-builtins and
-finclude-default-header.
This changes the behaviour of -finclude-default-header when
-fdeclare-opencl-builtins is specified: instead of including the full
header, it will include the header with only the base definitions.
