[LICM] Hoist loads that are dominated by invariant.start intrinsic, and are invariant in the loop.
Summary:
We can hoist out loads that are dominated by invariant.start, to the preheader.
We conservatively assume the load is variant, if we see a corresponding
use of invariant.start (it could be an invariant.end or an escaping
call).
