Jon Roelofs 785dc76c66 [llvm][SelectionDAG] Fix up chains in lowerInvokeable. rdar://113994760 (#94004) ...

lowerInvokeable wasn't updating the returned chain after emitting the
lowerEndEH, which caused SwiftErrorVal-handling code to re-set the DAG
root, and thus accidentally skip the EH_LABEL node it was supposed to
have addeed. After fixing that, a few places needed to be adjusted that
assume the specific shape of the returned DAG.
