Refactor to create the Semantics class that is responsible for holding state during semantics (the scope tree and messages) and managing the logic of the various phases of semantic processing. Eliminate static Scope::globalScope. The messages generated during semantic processing are accumulated in a Messages data member of Semantics so that individual phases don't need to emit them to std::cerr. This is now done by the driver so that it has control over where they go and eliminates other includes of iostream. To do this, the messages object is passed in to the various semantics operations. Move DumpSymbols into semantics.cc: it doesn't belong in resolve-names.cc and it depends on the global scope, so it's as good a place as any. The call to RewriteParseTree is also moved to Semantics.
