Log:
[41/77] Split scalar integer handling out of force_to_mode

force_to_mode exits partway through for modes that aren't scalar
integers.  This patch splits the remainder of the function out
into a subroutine, force_int_to_mode, so that the modes from that
point on can have type scalar_int_mode.

The patch also makes sure that xmode is kept up-to-date with x
and uses xmode instead of GET_MODE (x) throughout.

	* combine.c (force_int_to_mode): New function, split out from...
	(force_to_mode): ...here.  Keep xmode up-to-date and use it
	instead of GET_MODE (x).
