Subject: 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
