wcc/ww: nodefnptr keys the bare-ident arm on the stamped type

Browse Source 
nodefnptr matched bare idents by NAME against the fn table, so a
global var colliding with a fn leaf classified as a fn pointer —
wwstage silently built what cstage rejects at link (review finding
#14). Key on the stamped type; the #124 &mod.fn arm is preserved.
989_fnptrcollide_run pins both stages reject (red 1/2 pre-fix:
wwstage built rc=7).
