testsuite: Replace altivec vector attribute with generic equivalent [PR112822]

Usage of the altivec vector attribute requires use of the -maltivec option.
Replace with a generic equivalent which allows building the test case on
multiple other targets and non-altivec ppc cpus, but still diagnoses the
ICE on unfixed compilers.
