wcc/ww: &fn synthesis prefers the current module's fn

Browse Source 
The address-of-fn synthesis used a bare lookup — import order could
bind a same-leaf fn from another module, silently LEAQ-ing the wrong
function into a fn-ptr slot. Prefer the current module (mirror
check.c:410/1305). Report item #4 (loud and silent faces pinned).
