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.

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.

Many non-language extensions are defined but also unused. This patch
removes them with their tests as they do not require compiler support.
The cl_khr_select_fprounding_mode extension is also removed because it
has been deprecated since OpenCL 1.1 and Clang doesn't have any specific
support for it.
The cl_khr_context_abort extension is only referred to in "The OpenCL
Specification", version 1.2 and 2.0, in Table 4.3, but no specification
is provided in "The OpenCL Extension Specification" for these versions.
Because it is both unused in Clang and lacks specification, this
extension is removed.
The following extensions are platform extensions that bring new OpenCL
APIs but do not impact the kernel language nor require compiler support.
They are therefore removed.
- cl_khr_gl_sharing, introduced in OpenCL 1.0
- cl_khr_icd, introduced in OpenCL 1.2
- cl_khr_gl_event, introduced in OpenCL 1.1
Note: this extension adds a new API to create cl_event but it also
specifies that these can only be used by clEnqueueAcquireGLObjects.
Hence, they cannot be used on the device side and the extension does
not impact the kernel language.
- cl_khr_d3d10_sharing, introduced in OpenCL 1.1
- cl_khr_d3d11_sharing, introduced in OpenCL 1.2
- cl_khr_dx9_media_sharing, introduced in OpenCL 1.2
- cl_khr_image2d_from_buffer, introduced in OpenCL 1.2
- cl_khr_initialize_memory, introduced in OpenCL 1.2
- cl_khr_gl_depth_images, introduced in OpenCL 1.2
Note: this extension is related to cl_khr_depth_images but only the
latter adds new features to the kernel language.
- cl_khr_spir, introduced in OpenCL 1.2
- cl_khr_egl_event, introduced in OpenCL 1.2
Note: this extension adds a new API to create cl_event but it also
specifies that these can only be used by clEnqueueAcquire* API
functions. Hence, they cannot be used on the device side and the
extension does not impact the kernel language.
- cl_khr_egl_image, introduced in OpenCL 1.2
- cl_khr_terminate_context, introduced in OpenCL 1.2
The minimum required OpenCL version used in OpenCLExtensions.def for
these extensions is not always correct. Removing these address that
issue.

Rename lang mode flag to -cl-std=clc++/-cl-std=CLC++
or -std=clc++/-std=CLC++.
This aligns with OpenCL C conversion and removes ambiguity

Summary:
For OpenCL 1.1 embedded profile 64 bit integers i.e. long,
ulong including the appropriate vector data types and operations
on 64-bit integers are optional. The "cles_khr_int64" extension
string will be reported if the embedded profile implementation
supports 64-bit integers.
