[LV] Check all users of partial reductions in chain have same scale. (#162822)
Check that all partial reductions in a chain are only used by other
partial reductions with the same scale factor. Otherwise we end up
creating users of scaled reductions where the types of the other
operands don't match.
A similar issue was addressed in
https://github.com/llvm/llvm-project/pull/158603, but misses the chained
cases.
Fixes https://github.com/llvm/llvm-project/issues/162530.
