  [DebugInfo][GVN] Propagate DebugLoc from load-of-select to select (#114233)

When replacing a load from a selected pointer with a select of the known
stored values, we currently assign no DebugLoc to the select; this patch
propagates the load's DebugLoc to the new select, since it is a direct
replacement.
