Hojun-Cho 90452a8364 wcc/cgen: route same-type tagged-cast return through the widener (wwstage align to cstage) ...

A same-type tagged cast return (`return x: u`, u == fnret) emitted tag=0
(a 2nd-variant value returned the wrong payload). Route it through the
widener (needswiden when N_CAST && ru1==fu1, beside S1's ru1!=fu1) which
peels the identity cast internally -> correct; same-type non-cast stays on
the passthrough. Byte-id-neutral. test/wcc/837.
