// `.len` field-read on an array whose dimension is a
// `def` constant (`[MAX]T`) must resolve the length from the type table, the
// cgdot sibling of the #21 cgslice fix, migrated from
// test/wcc/989_defdim_field_run.c (#56). A `def MAX` dim arrives as a
// non-literal node; wwstage's cgdot `.len` arms (local / let-global / def) +
// letemitsize only handled an N_INTLIT dim, so `.len` folded to MOVQ $0 (ww
// returned 0 where cstage reads the resolved bu->alen). The fix reads alen from
// the stamped array tinfo (rule-13) in each arm. cstage was always correct; T2
// (test-lang-byteid) keeps the cs==ww net the .c twin's run-compare provided.
