Factor out core linking options from Platform in a new ResolverOptions

class.  Change Resolver to no longer use Platform.  Core linking
now issues errors directly.  We need to factor that out later.

Rework how Darwin executable writer finds "main" atom.  It now
adds to core linking an Atom  which has a Reference to "main".
