<pre>A fixed version of this change landed as:
Sending lib/Transforms/InstCombine/InstCombineLoadStoreAlloca.cpp
Sending test/Transforms/InstCombine/atomic.ll
Transmitting file data ..
Committed revision 268809
For context, it's interesting to note that the case we were crashing in was
actually a miscompile without this change. We happily rewrote the types of the
volatile store (which my assert triggered on), but dropped the atomicity and
volatility when doing so. I added test cases to prevent us getting this wrong
in the future.</pre>
