Build problem with R9C-0

This problem seems to have to do with the shared heap. It seems that you
get the hipe_literals.hrl file that is produced when making the shared
emulator. I think you can solve this problem by changing your:
erts/emulator/hipe/hipe_mkliterals.c
and
lib/hipe/rtl/hipe_tagscheme.erl
to the ones I've attached to this mail.
