These are standard HiPE wrappers for standard BIFs or primops.
They should be listed in the generated erl_bif_list.h file like this

BIF_LIST(am_erlang,am_append_element,2,append_element_2,288)

from which the hipe_x86_bifs.m4 file will construct an appropriate
wrapper in the generated hipe_x86_bifs.S file. Please check that
they occur in both erl_bif_list.h and hipe_x86_bifs.S. If they do
occur in hipe_x86_bifs.S, then check that they are defined as global
symbols in hipe_x86_bifs.o (nm hipe_x86_bifs.o | grep append_element_2).
