In this PR, we support for dereferencing void pointers as a GNU C extension. This include two modification: - In CIRGen, we support to build ReturnStmt with void return type. - In LowerToLLVM, we support to lower CIR load with void result type to LLVM. It's a part of #579, since I would like to split it to two tasks: - support pointer arithmetic for function types (#594) - **support to dereference void pointer (this PR)**

…m#594) Same as void pointers `void *`, we treat function pointer arithmetic as `GEP i8`, according to the original behavior of clang ([godbolt](https://godbolt.org/z/EMdvfdTe7)).
