w6c+selfhost: cgen chained N_DOT/N_ASSIGN spine walk

Browse Source 
Loop-shaped spine walker for value-struct chains (o.i.a) and slice/str
pseudo-fields (s.buf.len), read+write, both stages. SB-fallback at the
catch-all preserved for unresolved module-qualified idents.

Follow-ups filed: tasks #7-#10 (wwstage >6-arg frame over-alloc, chained
array-elem field BX loss, & through chained DOT, signed sub-word field
loads zero-extend).
