[58/77] Use scalar_int_mode in a try_combine optimisation
This patch uses scalar_int_modes for:
/* If I2 is setting a pseudo to a constant and I3 is setting some
sub-part of it to another constant, merge them by making a new
constant. */
This was already implicit, but the danger with checking only
CONST_SCALAR_INT_P is that it can include CC values too.

* combine.c (try_combine): Use is_a <scalar_int_mode> when
trying to combine a full-register integer set with a subreg
integer set.
