RM: obsolete intel opencl libraries (for llvm-11, -13)

[Timo Aaltonen]

These should be removed, we have versions for llvm-14 in the archive which is the default for this stack.

[Steve Langasek (vorlon)]

In fact, three of these I removed today following their removal from Debian.

Unfortunately, for the last one it hasn't been removed because despite Debian saying it's no longer used, reverse-depends appears to disagree:

Reverse-Depends
* libllvmspirvlib-11-dev (for libllvmspirvlib11)
* libopencl-clang11 (for libllvmspirvlib11)
* libopencl-clang13 (for libllvmspirvlib13)
* llvm-spirv-11 (for libllvmspirvlib11)

Packages without architectures listed are reverse-dependencies in: amd64, arm64, armhf, ppc64el, s390x

Reverse-Build-Depends
* llvm-toolchain-13 (for llvm-spirv)
* llvm-toolchain-14 (for llvm-spirv)

so I don't see that we can remove this from Ubuntu. If I'm missing some reason this doesn't break the named reverse-dependencies, please clarify here.

yeah looks like we'll have llvm-13 to clean up until next release, and llvm should use the matching llvm-spirv right from the start but oh well

[Steve Langasek (vorlon)]

ok closing this as invalid as I expect there's nothing else for the archive admins to track, spirv-llvm-translator should fall out of the archive once it's no longer used in kinetic+1
