;; Image types may be represented in two ways while translating to SPIR-V:
;; - OpenCL form based on pointers-to-opaque-structs, e.g. '%opencl.image2d_ro_t',
;; - SPIR-V form based on TargetExtType, e.g. 'target("spirv.Image", void, 1, 0, 0, 0, 0, 0, 0)',
;; but it is still one type which should be translated to one SPIR-V type.
;;
;; The test checks that the code below is successfully translated and only one
;; SPIR-V type for images is generated.
