Verified the patch also fixes the problem with h264ref benchmark.

--- Comment #28 from Alan Modra ---
Bootstrapped and regression testing now completed on both powerpc64le-linux and
-m64/-m32 on a power7 powerpc64-linux host, all langs. No regressions found,
and it seems this also fixes

However, that was with the parentheses misplaced. I've completed a bootstrap

Ah, I see from IRC that Alan has already done a regstrap and reported no

But that's ok - we are storing the same scalar element:

The most suspicious thing I see in r224221 is following the gap adjustment:
vect__39.29_261 = REALIGN_LOAD ;
vectp_s.20_260 = vectp_s.20_278 +
