  [VectorCombine] shuffleToIdentity - guard against call instructions.

The shuffleToIdentity fold needs to be a bit more careful about the difference
between call instructions and intrinsics. The second can be handled, but the
first should result in bailing out. This patch also adds some extra intrinsic
tests from #91000.

Fixes #91078
