wcc: narrow integer pointer-deref load width via localloadop (#116)

Browse Source 
TK_STAR integer arm now routes through localloadop (cstage cgen.c) /
localloadop (wwstage cgenexpr.ww) — load-twin of the landed signed-
narrow-scalar-reads fix, was omitting TK_STAR. Closes the *p (CMPQ,
full-width arith) miscompile family (#116 + 962/963 instances all
fixed by the same width-aware load). Float arm untouched (#96 already
routed via X0). New test 947 (10 rows): packed CMPQ + signed/unsigned
narrow widths + TY_NAMED/TBANG alias + TY_ENUM peel + i64/bool controls.
