Re-apply "[JumpThreading] Ignore free instructions"
It seems the crashes we saw wasn't caused by this (see comments on the review).
> This is basically D108837 but for jump threading. Free instructions
> should be ignored for the threading decision. JumpThreading already
> skips some free instructions (like pointer bitcasts), but does not
> skip various free intrinsics -- in fact, it currently gives them a
> fairly large cost of 2.
