Use of strings with code points over 0xFF as arguments to "vec"

Implement scheduled fatalization.  Adapt existing tests in t/op/vec.t.
Eliminate t/lib/warnings/doop and move one test to t/op/vec.t.

Document this fatalization in perldiag and perlfunc.

Documentation improvement recommended by Karl Williamson.
