HiPE's range analysis would not update the arguments of a callee when
the result of the call was ignored.

Fixes ERL-278.

erl_bif_types contains a fixed and improved copy-paste (obvious from the
dead Max_range2_leq_zero if branches) of hipe_icode_range:range_rem/2.
For now, delete the dead code and propagate back fixes and improvements
to hipe_icode_range.

 * Omit bounds check in more cases.
   A test case that needs this change to omit bounds check is added.
 * Improve code generation by reformulating bounds check to decrease
   register pressure.

This is useful to generate shorter code for closures generated by
(fun F/A).
