gcc.dg/tree-ssa/predcom-8.c fails on aarch64 for the reasons discussed
in the PR trail. The fix didn't make it into GCC 15, so this patch
XFAILs the test instead.
Other targets might benefit from an XFAIL too, but people who work on
those targets would be better placed to know the right conditions.
Tested on aarch64-linux-gnu. OK for GCC 15?
FWIW, I was holding off on doing this in case the patch did make it in.
With the patch applied, I get clean results locally on aarch64-linux-gnu
for all testsuites except libphobos, where the some math routines are
missing AArch64 support.
