; Image types may be represented in two ways while translating to SPIR-V:
; - OpenCL form, for example, '%opencl.image2d_ro_t',
; - SPIR-V form, for example, '%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.
