[DAG] isSplatValue - only treat binop splats shared undef elements as undef (#135597)
#134602 demonstrated an issue where an AND node always had at least one demanded UNDEF element in either operand, and incorrectly reported this an all-undef result - despite the other element being 0 (so would correctly fold to 0).
This fix only assumes a binops splats element is undefined if both operands are undef.
Fixes #134602
