First patch

First implementation with compile-time resolution

Todo:
- Handle run-time solution - I do not yet know how to handle it best.
  One solution is to use effectively  [ (bessel_jn(i,x), i=n1, n2) ]
  but the question is where; maybe in simplify, but then one needs to
  generate a temporary symbol which does not clash with others.
  Cf. array.c's match_array_list for an ac-implied-do
- Test cases
- Documentation (cf. also PR 36096)
