This pull request aims to remove any dependency on OpenCL/SPIR-V type information in LLVM IR metadata. While, using metadata might simplify and prettify the resulting SPIR-V output (and restore some of the information missed in the transformation to opaque pointers), the overall methodology for resolving kernel parameter types is highly inefficient. The high-level strategy is to assign kernel parameter types in this order: 1. Resolving the types using builtin function calls as mangled names must contain type information or by looking up builtin definition in SPIRVBuiltins.td. Then: - Assigning the type temporarily using an intrinsic and later setting the right SPIR-V type in SPIRVGlobalRegistry after IRTranslation - Inserting a bitcast 2. Defaulting to LLVM IR types (in case of pointers the generic i8* type or types from byval/byref attributes) In case of type incompatibility (e.g. parameter defined initially as sampler_t and later used as image_t) the error will be found early on before IRTranslation (in the SPIRVEmitIntrinsics pass).
