clang-p2996/llvm/test/Transforms/SLPVectorizer/X86/extractelement-single-use-many-nodes.ll
Alexey Bataev 48bbd76587 [SLP]Fix PR79229: Check that extractelement is used only in a single node 
before erasing.

Before trying to erase the extractelement instruction, not enough to
check for single use, need to check that it is not used in several nodes
because of the preliminary nodes reordering.
