  [SLP]Fix PR87329: crash on alternate cast vectorization.

Need to fix the analysis for the alternate instructions, based on int
extension operations. If the alternate extension node is resized, but
not the operand, need to resize the node and do not shuffle final
result, we end up only with trunc instruction.
