.cap on a fixed-size array is invalid (Hare has no capacity-read; arrays can't grow) -> both stages now loud-reject at the checker. wwstage was silently returning frame garbage for a local array's .cap; cstage typed it then vaguely rejected at use. Unified to one early checker reject with an identical diagnostic both stages. .ptr on a fixed-size array is ratified VALID: array.ptr is &A[0], a sanctioned ww spelling divergence from Hare; see task #13. The toolchain already relies on it in 14 backing-pointer sites. WHY-doc added at both checker .ptr-on-array sites. The def-global .ptr cgen base-selection bug (#11) is a separate following commit. Valid-program asm unchanged (byte-id 990-997 8/8); w6c/w6c_ww binaries move (checker code changed). test/wcc/817 table-driven, model 684.
