示例1: performNameBinding
/// performNameBinding - Once parsing is complete, this walks the AST to
/// resolve names and do other top-level validation.
///
/// At this parsing has been performed, but we still have UnresolvedDeclRefExpr
/// nodes for unresolved value names, and we may have unresolved type names as
/// well. This handles import directives and forward references.
void swift::performNameBinding(SourceFile &SF, unsigned StartElem) {
// Make sure we skip adding the standard library imports if the
// source file is empty.

// Reset the name lookup cache so we find new decls.
// FIXME: This is inefficient.
