Backport to gcc-9: PR92398: Fix testcase failure of pr72804.c
Backport the patch to fix failures on P9 and P8BE, P7LE for PR94036.
Tested pass on P9/P8/P7.
(gcc-8 is not needed as the test doesn't exists.)
P9LE generated instruction is not worse than P8LE.
mtvsrdd;xxlnot;stxv vs. not;not;std;std.
It can have longer latency, but latency via memory is not so critical,
and this does save decode and other resources. It's hard to choose
which is best. Update the test case to fix failures.
