  [mlir] Guard sccp pass from crashing with different source type (#120656)

Vector::BroadCastOp expects the identical element type in folding. It
causes the crash if the different source type is given to the SCCP pass.
We need to guard the pass from crashing if the nonidentical element type
is given, but still compatible. (e.g. index vs integer type)
