Nirav Dave 123be93bcd Preserve DebugInfo when replacing values in DAGCombiner ...

Recommiting after fixing over-aggressive assertion

[DAG] Previously debug values would transfer debuginfo for the selected
start node for a replacement which allows for debug to be dropped.

Push debug value transfer to occur with node/value replacement in
SelectionDAG, remove now extraneous transfers of debug values.

This refixes PR9817 which was being incompletely checked in the
testsuite.
