[REGRESSION][PATCH V4 1/3] bpf jit: Make the filter.c::__load_pointerhelper non-static for the jits

[Jan Seiffert]

The function is renamed to make it a little more clear what it does.
It is not added to any .h because it is not for general consumption, only for
bpf internal use (and so by the jits).
