Revert "[JumpThreading] Ignore free instructions"
It caused compiler crashes, see comment on the code review for repro.
> 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.
