Write dedicated tests for foldSelectValueEquivalence, demonstrating that it does not perform many GVN-like replacements on vector-values, as a prelude to fixing this deficiency.
foldSelectEquivalence has an artificial limitation around checking that the compare-instruction is not a vector type. Trivially lifting this limitation does not lead to any bad test changes.
