This patch fixes out the GEN_INT/gen_int_mode that Richard pointed out
in the wide-int review. It also passes "mode" rather than "VOIDmode"
to immed_double_int_const. (As discussed in that thread, the latter
change shouldn't make any difference in practice, but is still more
correct in principle.)
Bootstrapped & regression-tested on x86_64-linux-gnu. OK to install?

* explow.c (plus_constant): Pass "mode" to immed_double_int_const.
Use gen_int_mode rather than GEN_INT.
