Backport #8513: assertion failed in rb_ary_modify

-DARRAY_DEBUG をつけていると rdoc の生成中に array.c:282 で assertion failed になります。

    else if (ARY_SHARED_NUM(shared) == 1 && len > (RARRAY_LEN(shared)>>1)) {          
        long shift = RARRAY_PTR(ary) - RARRAY_PTR(shared);                            
        ARY_SET_PTR(ary, RARRAY_PTR(shared));                                         
        ARY_SET_CAPA(ary, RARRAY_LEN(shared));                                        

の ARY_SET_CAPA が assertion failed になっている 282 行目で、ARY_SET_PTR は通っているので、共通している
assert(!ARY_EMBED_P(ary));
assert(!OBJ_FROZEN(ary));
は問題なくて
assert(!ARY_SHARED_P(ary));
でひっかかっているようです。

* array.c (FL_SET_EMBED): shared object is frozen even when get
  unshared.

* array.c (rb_ary_modify): ARY_SET_CAPA needs unshared array.
