This commits adds the minimal required bits to build a logical SPIR-V compute shader using LLC. - Skip OpenCL-only capabilities & extensions for Logical SPIR-V. - Generate required metadata for entrypoints from HLSL frontend. - Fix execution mode to GLCompute in logical. The main issue is the lack of "vulkan" bit in the triple. This might need to be added as a vendor? Because as-is, SPIRV32/64 assumes OpenCL, and then, SPIRV assumes Vulkan. This is ok-ish today, but not correct. Differential Revision: https://reviews.llvm.org/D156424
