Hojun-Cho d66aef382a w6c+selfhost: cgen *T-rooted chained N_DOT (closes #22) ...

Spine walker now accepts *T root at the last hop (cur->lhs->kind ==
N_IDENT, pu->kind == TY_PTR), substitutes pointee struct, emits
MOVQ off(BP), CX before offset arithmetic. Symmetric in N_DOT and
N_ASSIGN. Distinct gate from existing mid-chain *T-field branch
(cgen.c:4615) — no shadow.

Unblocks task #18 (bufio writer first-field embed). Pre-existing
*T-field mid-chain path unchanged.
