This patch adds a helper method to determine if a nonvirtual base has an entry
in the LLVM struct. Such a base may not have an entry
if the base does not have any fields/bases itself that would change the size of
the struct. This utility method is useful for other frontends (Polygeist) that
use Clang as an API to generate code.
