Simplify minsym iteration
This simplifies the minimal symbol iterator, by using
minimal_symbol_count and just doing a somewhat ordinary array-like
iteration. array_view is nearly usable, except that it is more
convenient for this iterator to return pointers rather than
references.

type. Remove no-argument constructor.
