Upstream ClangIR support for `void` type, floating-point types, pointer types, and function types. Floating-point support is missing the IBM double-double format, because that hasn't been implemented in the incubator project yet. Pointer types do not yet support address spaces. Function type support includes only the return type and the parameter types. The many other properties and attributes of function types will be upstreamed later.
