Add typeid_for_trait_ref function
This function computes a Itanium-like typeid for a trait_ref. This is required for the VFE optimization in LLVM. It is used to map `llvm.type.checked.load` invocations, that is loading the function from a vtable, to the vtables this function could be from. It is important to note that `typeid`s are not unique. So multiple vtables of the same trait can share `typeid`s.
