[PATCH] D141008: [Clang][SPIR-V] Emit target extension types for OpenCL types on SPIR-V.

jcranmer-intel added a comment.

Most of the testing for this change has been in conjunction with the changes in the SPIRV-LLVM-Translator repository here: https://github.com/KhronosGroup/SPIRV-LLVM-Translator/pull/1799. I haven't updated the in-tree experimental target to support the target-extension types, but I did want to provide more documentation as to how these types work in the existing LLVM documentation for the SPIR-V backend.

There's still a few issues with this patch. First, I've made the use of these types unconditional for the SPIR-V target--it may be more appropriate to make these triggered off of a hidden option defaulted to off for now, or maybe based on whether or not opaque pointers are enabled. The other issue is the cast_image.cl test which... does an illegal operation in SPIR-V, and looking at the history of the test, doesn't seem to really test what it's claiming to test (https://reviews.llvm.org/D22927 was the revision it was adding tests for). I disabled the test for now for SPIR-V out of ignorance of which way to go about for fixing this test.
