This patch adds support for TargetExtType/target(...) representing SPIR-V builtin types. After D135202, target(...) is the preferred way for representing SPIR-V builtin types in LLVM IR and the only working in the opaque pointer mode. In order to maintain compatibility with LLVM IR generated by older versions of Clang and LLVM/SPIR-V Translator, pointers-to-opaque-structs denoting SPIR-V/OpenCL builtin types will be translated to equivalent SPIR-V target extension types. This translation is only available in the typed pointer mode (-opaque-pointers=0). The relevant LIT tests with SPIR-V builtins were converted to use the new target(...) notation.

;; 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.
