hipe: remove two obsolete BIFs

The hipe_bifs:make_native_stub/2 and hipe_bifs:get_emu_address/1
BIFs were originally used by hipe_unified_loader.erl, but the
code been obsolete and disabled for ages.

Remove the BIFs and all references to them.

In hipe_unified_loader.erl, remove the no-op emu_make_stubs/1
function.
