[PR testsuite/116860] Testsuite adjustment for recently added tests

There's two new tests that are dependent on logical-op-non-short-circuit
settings.  The BZ is reported against ppc64 and ppc64le, but also applies to a
goodly number of the other targets.

The "regression" fix is trivial, just add the appropriate param to force the
behavior we're expecting.  I'm committing that fix momentarily.  It's been
verified on ppc64, ppc64le and x86_64 as well as the various embedded targets
in my tester where many FAILS flip to PASS.

I'm leaving the bug open without the regression marker as Jakub has noted a
couple of improvements that we can and probably should make.
