  [SLP]Fix insert point for copyable node with the last inst, used only outside the block

If the copyable entry has the last instruction, used only outside the
block, tha insert ion point for the vector code should be the last
instruction itself, not the following one. It prevents wrong def-use
sequences, which might be generated for the buildvector nodes.

Fixes #163404
