Website needs update

[mfwitten]

Please update this website:

• https://www.khronos.org/opencl/

Currently, it leads newcomers down an old path to a dead end; it needs to point them instead to the following facts (as far as I can tell):

• The official clang project is now the home of OpenCL front-end development; it can target particular devices or the LLVM bitcode.

• Khronos Group's role is developing tools to translate LLVM bitcode to SPIR-V bitcode (and vice versa); this work is held in the SPIRV-LLVM-Translator repo.

• Intel is developing "Common clang" (seriously?) that uses both clang and SPIRV-LLVM-Translator projects to provide an OpenCL-specific command-line interface to clang, and which thereby produces SPIR-V output from OpenCL input (without having to fiddle with any other intermediate representation).

Hi @mfwitten, I think this issue should be transferred into KhronosGroup/OpenCL-Registry repo that actually contains the content of mentioned website and since it is open-source too, you could suggest your changes via pull request there

Fix the website.

+@pierremoreau suggestions on LLVM-SPIRV repository updates in addition to the Khronos web-page.
KhronosGroup/SPIRV-LLVM#238 (comment)

We have updated the link to the translator in the resources page and archived outdated SPIRV-LLVM repo. I'm going to close this now as fixed.

If there are other requests to improve the site, they should be posted in the corresponding repo
