The callers of do_jump_by_parts_* had already established
that the modes were MODE_INTs, so this patch passes the
modes down as scalar_int_modes.

* dojump.c (do_jump_by_parts_greater_rtx): Change the type of
the mode argument to scalar_int_mode.
(do_jump_by_parts_zero_rtx): Likewise.
(do_jump_by_parts_equality_rtx): Likewise.
(do_jump_by_parts_greater): Take a mode argument.
(do_jump_by_parts_equality): Likewise.
(do_jump_1): Update calls accordingly.
