Sven van Haastregt 612d0ef173 [OpenCL] Move remaining defines to opencl-c-base.h
Move any remaining preprocessor defines from `opencl-c.h` to
`opencl-c-base.h`, such that they are shared with
`-fdeclare-opencl-builtins` too.

In particular, move:
 - the `as_type` and `as_typen` definitions, and
 - the `kernel_exec` and `__kernel_exec` definitions.

Also clang-format the changes.

Sven van Haastregt 5a4a01460f [OpenCL] Move printf declaration to opencl-c-base.h
Supporting `printf` with `-fdeclare-opencl-builtins` would require
special handling (for e.g. varargs and format attributes) for just
this one function.  Instead, move the `printf` declaration to the
shared base header.

Anastasia Stulova a84599f177 [OpenCL] Implement extended subgroups fully in headers.
Extended subgroups are library style extensions and therefore
they require no changes in the frontend. This commit:
1. Moves extension macro definitions to the internal headers.
2. Removes extension pragmas because they are not needed.

Sven van Haastregt f0c690018a [OpenCL] Stop opencl-c-base.h leaking extension enabling
opencl-c.h disables all extensions at its end, but opencl-c-base.h
does not, and that causes any inclusion of only opencl-c-base.h to
leave some extensions (such as cl_khr_fp16) enabled.  This affects the
-fdeclare-opencl-builtins option for example.

This violates the OpenCL Extension Specification which specifies that
"The initial state of the compiler is as if the directive #pragma
OPENCL EXTENSION all : disable was issued".

Fix by disabling all extensions at the end of opencl-c-base.h and
enable extensions inside opencl.h which relied on opencl-c-base.h
enabling the cl_khr_fp16/64 extensions.

Anastasia Stulova ef58804ebc [OpenCL] Fix lang mode predefined macros for C++ mode.
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.

Sven van Haastregt e9e59ad79f [OpenCL] Define CLK_NULL_EVENT without cast
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.

Sven van Haastregt b502a44110 [OpenCL] Restore ATOMIC_VAR_INIT
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.

Sven van Haastregt af1c230e70 [OpenCL] Split type and macro definitions into opencl-c-base.h
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.
