wcc/ww: paramfieldsize sizes slice/tuple fields through the type table

Browse Source 
for-range destructure of an element with a slice- or tuple-typed field
strode by the default 8 (paramfieldsize had no N_TSLICE/N_TTUPLE arms),
silently reading the wrong words (review finding #43; live repro
cs=42 vs ww=8). Add the arms routed through tinfo per rule 13.
989_tupfieldsize_run pins cs==ww (red 1/2 pre-fix); rows assert
convergence, not absolutes — cstage's own single-word destructure-load
bug is filed as task #40. The N_TARRAY arm is deferred (task #39,
rule-7 comment at the fall-through).
