Alex Zinenko 5e7959a353 Use llvm.func to define functions with wrapped LLVM IR function type ... This function-like operation allows one to define functions that have wrapped LLVM IR function type, in particular variadic functions. The operation was added in parallel to the existing lowering flow, this commit only switches the flow to use it. Using a custom function type makes the LLVM IR dialect type system more consistent and avoids complex conversion rules for functions that previously had to use the built-in function type instead of a wrapped LLVM IR dialect type and perform conversions during the analysis.
