David Majnemer fb8ef4867c [MergedLoadStoreMotion] Don't transform across may-throw calls 
It is unsafe to hoist a load before a function call which may throw, the
throw might prevent a pointer dereference.

Likewise, it is unsafe to sink a store after a call which may throw.
The caller might be able to observe the difference.

This fixes PR27858.
