75ef0be0 - [SLP]Be careful when trying match/vectorize copyable nodes with external uses only

[SLP]Be careful when trying match/vectorize copyable nodes with external uses only Need to be careful when trying to match and/or build copyable node with the instructions, used outside the block only and if their operands immediately precede such instructions. In this case insertion point might be the same and it may cause broken def-use chain. Fixes #167366
