wcc/ww: global float-struct by-value arg keys the SSE drain off the type

Browse Source 
A module-global float-bearing struct passed by value drained all-GP —
the SSE-cursor classify keyed on the node shape and missed the global
ident; key off the stamped struct type (per-eightbyte classify,
F7-flavored stamp fix). Review item #31; dual-stage rows red-proven.
