Keith Randall 0153a4130d cmd/compile: fix runtime.KeepAlive
KeepAlive needs to introduce a use of the spill of the
value it is keeping alive.  Without that, we don't guarantee
that the spill dominates the KeepAlive.

This bug was probably introduced with the code to move spills
down to the dominator of the restores, instead of always spilling
just after the value itself (CL 34822).

Fixes #22458.
