--- Comment #1 from Dimitry Andric <dim at FreeBSD.org> ---
I'm taking a look at this.  Bisection shows that the following upstream
revision breaks those particular tests:

https://reviews.llvm.org/rL329339

"[X86] Remove some InstRWs for plain store instructions on Sandy Bridge."

Not sure yet why this particular change causes the test results to be
different.
