Nikita Popov 9ecb90821e [InstCombine] Support ssub.sat canonicalization for non-splats ...

Extend ssub.sat(X, C) -> sadd.sat(X, -C) canonicalization to also
support non-splat vector constants. This is done by generalizing
the implementation of the isNotMinSignedValue() helper to return
true for constants that are non-splat, but don't contain any
signed min elements.
