Justin Lebar d791dcafe4 [LSV] Don't move stores across may-load instrs, and loosen restrictions on moving loads. ...

Summary:
Previously we wouldn't move loads/stores across instructions that had
side-effects, where that was defined as may-write or may-throw.  But
this is not sufficiently restrictive: Stores can't safely be moved
across instructions that may load.

This patch also adds a DEBUG check that all instructions in our chain
are either loads or stores.
