combine: Fix problem with RTL checking · 08223f76

As Jakub found, after my recent combine patch at least on x86 problems
show up with RTL checking enabled.  This is because the I2 generated
by a successful instruction combination can write not only a register
but it can also write a paradoxical subreg of one.

This fixes it.


	* combine.c (try_combine): When adjusting LOG_LINKS for the destination
	that moved to I2, also allow destinations that are a paradoxical
	subreg (instead of a normal reg).
