David Majnemer 62690b1952 [SROA] Don't de-atomic volatile loads and stores 
Volatile loads and stores are made visible in global state regardless of
what memory is involved.  It is not correct to disregard the ordering
and synchronization scope because it is possible to synchronize with
memory operations performed by hardware.

This partially addresses PR23737.
