Anastasia Stulova 58984e7087 [OpenCL] Correct ndrange_t implementation
Removed ndrange_t as Clang builtin type and added
as a struct type in the OpenCL header.

Use type name to do the Sema checking in enqueue_kernel
and modify IR generation accordingly.

Anastasia Stulova d1f390ef99 [OpenCL] Diagnose write_only image3d when extension is disabled
Prior to OpenCL 2.0, image3d_t can only be used with the write_only
access qualifier when the cl_khr_3d_image_writes extension is enabled,
see e.g. OpenCL 1.1 s6.8b.

Require the extension for write_only image3d_t types and guard uses of
write_only image3d_t in the OpenCL header.

Yaxun Liu 2e8331cab6 [OpenCL] Allow disabling types and declarations associated with extensions
Added a map to associate types and declarations with extensions.

Refactored existing diagnostic for disabled types associated with extensions and extended it to declarations for generic situation.

Fixed some bugs for types associated with extensions.

Allow users to use pragma to declare types and functions for supported extensions, e.g.

#pragma OPENCL EXTENSION the_new_extension_name : begin
// declare types and functions associated with the extension here
#pragma OPENCL EXTENSION the_new_extension_name : end

Yaxun Liu 7d07ae7c85 [OpenCL] Mark group functions as convergent in opencl-c.h
Certain OpenCL builtin functions are supposed to be executed by all threads in a work group or sub group. Such functions should not be made divergent during transformation. It makes sense to mark them with convergent attribute.

The adding of convergent attribute is based on Ettore Speziale's work and the original proposal and patch can be found at https://www.mail-archive.com/cfe-commits@lists.llvm.org/msg22271.html.

Anastasia Stulova 7c30533362 [OpenCL] Diagnose variadic arguments
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.

Anastasia Stulova db7a31cce7 [OpenCL] An implementation of device side enqueue (DSE) from OpenCL v2.0 s6.13.17.
- Added new Builtins: enqueue_kernel, get_kernel_work_group_size
and get_kernel_preferred_work_group_size_multiple.

These Builtins use custom check to diagnose parameters of the passed Blocks
i. e. variable number of 'local void*' type params, and check different
overloads specified in Table 6.31 of OpenCL v2.0.

- IR is generated as an internal library call for each OpenCL Builtin,
reusing ObjC Block implementation.

Yaxun Liu e8f49b9db7 [OpenCL] Add the default header file opencl-c.h for OpenCL C language
OpenCL has large number of "builtin" functions ("builtin" in the sense of OpenCL spec) which are defined in header files. To compile OpenCL kernels using these builtin functions, a header file is needed.

This header file is based on the Khronos implementation (https://github.com/KhronosGroup/SPIR/blob/spirv-1.0/lib/Headers/opencl.h) with heavy refactoring.

Re-commit after fixing failures on ppc64/systemz etc.
