erts-hipe: Change THE_NON_VALUE for HiPE enabled debug emulator
This is a work-around as there are hipe BIFs that return untagged
integers that may be intepreted as THE_NON_VALUE (24).
Hipe bifs that return offsets as untagged integers:
hipe_bs_put_utf8
hipe_bs_put_utf16be
hipe_bs_put_utf16le
Hipe bifs that return raw pointers:
hipe_find_na_or_make_stub
hipe_nonclosure_address
