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).
