The patch adds SPIRVPrepareFunctions pass, which modifies function signatures containing aggregate arguments and/or return values before IR translation. Information about the original signatures is stored in metadata. It is used during call lowering to restore correct SPIR-V types of function arguments and return values. This pass also substitutes some llvm intrinsic calls to function calls, generating the necessary functions in the module, as the SPIRV translator does. The patch also includes changes in other modules, fixing errors and enabling many SPIR-V features that were omitted earlier. And 15 LIT tests are also added to demonstrate the new functionality.
