Revert faecc736e2ac3cd8c77 #74443 [DAG] isSplatValue - node is a splat if all demanded elts have the same whole constant value (#74443)
Relying on ComputeKnownBits to find a splat is causing miscompilations where a shift of zero is being assumed to give zero, but further simplification leads to a shift of zero by undef, resulting in an unexpected undef value.
Fixes #78109
