Alexey Bataev 50822d6b25 [SLP]Do not request the last instruction for first buildvector nodes with no state ...

If looking for the match of the gather/buildvector node and its root is
a first node, which also a buildvector/gather, and has no state, we
should skip the analysis for such nodes to prevent a compiler crash

Fixes #185851
