Philip Reames c833b3773e Fix a *nasty* miscompile in experimental unordered atomic lowering ...

This is an omission in rL371441.  Loads which happened to be unordered weren't being added to the PendingLoad set, and thus weren't be ordered w/respect to side effects which followed before the end of the block.

Included test case is how I spotted this.  We had an atomic load being folded into a using instruction after a fence that load was supposed to be ordered with.  I'm sure it showed up a bunch of other ways as well.

Spotted via manual inspecting of assembly differences in a corpus w/and w/o the new experimental mode.  Finding this with testing would have been "unpleasant".
