location_force_reg() to force a set into a register, except
to a register of the same size as the set. The reason is
that on big endian systems, this would require moving the
set to the most significant part of the new register,
and location_force_register can't do that (it does not
know the type).
a_bit_test_reg_loc_reg() properly takes into account the
size of the set to adjust the register index to test }
