Rework the lazy function body parsing mechanism to use the request-evaluator, so that asking for the body of a function will initiate parsing. Clean up a number of callers to AbstractFunctionDecl::getBody() that don't actually need the body, so we don't perform unnecessary parsing. This change does not delay parsing of function bodies in the general case; rather, it sets up the infrastructure to always delay parsing of function bodies.
