The current implementation allocates a new {NativeModule} if trap
handlers are disabled. Afterwards, all export wrappers need to be
patched to call to the code objects in this new native module (this
patching is done in {CodeSpecialization}).
With the jump table, we want to get rid of this patching, hence we need
to reuse the same jump table, hence we cannot allocate a new
{NativeModule}. Instead, we should update the existing one with the new
code.
