SPIRV-LLVM-Translator project (https://github.com/KhronosGroup/SPIRV-LLVM-Translator) from Khronos Group is a tool and a library for bi-directional translation between SPIR-V and LLVM IR. In its backward translation from SPIR-V to LLVM IR SPIRV-LLVM-Translator isn't necessarily able to cover the same SPIR-V patterns/instructions set that SPIRV Backend produces, even if we target the same SPIR-V version in both SPIRV-LLVM-Translator and SPIRV Backend projects. To improve interoperability and ability to apply SPIRV Backend output in different products this PR introduces a notion of a mode of SPIR-V output that is compatible with a subset of SPIR-V supported by SPIRV-LLVM-Translator. This includes a new command line option that doesn't influence default behavior of SPIRV Backend and one test case that demonstrates how this command line option may be used to get a practical benefit of producing that one of two possible and similar output options that can be understood by SPIRV-LLVM-Translator.
