testsuite: XFAIL predcom-8.c on aarch64 [PR118407]

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.

	PR tree-optimization/118407
	* gcc.dg/tree-ssa/predcom-8.c: Add XFAIL for aarch64.
