[DAG] isSplatValue - only treat binop splats with repeated undef elements as undef (#135945)
#135597 didn't correctly fix the issue of binops with an undef element
from only one operand - only reporting the common undef elements could
incorrectly recognise splats where the (binop X, undef) fold might
actually be different - we need to ensure both operands have the same
demanded undefs for certainty.

Fixes #135917
