[SelectionDAG] Replace findGlueUse in SelectionDAGISel with SDNode::g…#120512

…etGluedUser. NFC
SDNode::getGluedUser has a little bit different implemenetation,
but the effect should be the same.
SDNode *getGluedUser() const {
for (use_iterator UI = use_begin(), UE = use_end(); UI != UE; ++UI)
if (UI.getUse().get().getValueType() == MVT::Glue)
return *UI;
return nullptr;
