To be honest, I don't see in the SPIR-V spec anything about environments being OpenCL/Vulkan. Anyway, I think what we are detecting here is capabilities because most uses of `isKernelEnv()/isShaderEnv()` are used to check if a particular feature is allowed --e.g. `Constant` decoration is only allowed if `Kernel` capability is enabled. Fundamentally, we want to know if we're dealing with graphical shaders or compute kernels.
