Log:
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 just checking
CONST_SCALAR_INT_P is that it can include CC values too.
