prefix-no-update.c should be fixed by the patch Segher proposed in PR103197.
pr56605.c got a wrong fixed and failed with GCC11. I will submit a patch to fix
it.

Looking through test results I see that gcc.target/powerpc/pr56605.c and
gcc.target/powerpc/prefix-no-update.c are still failing today.

Seurer,
Could you provide detail info about test? Such as config and build option. I
tested the build on P10 and no failure on parity_1.f90. Thanks.

For fusion-p10-ldcmpi.c and prefix-no-update.c, the optimization doesn't work
when mode promotion is disabled. I will do further investigation.

For pr56605.c, the pseudo is not taken mode promotion. The original combined
