* Add tests for early errors in functions * Improve tests for class accessors Use the `propertyHelper.js` utility in order to functionally test the property descriptors of class methods. * Remove redundant tests The semantics of an IdentifierReference as a PropertyDefinition within an object initializer are exhaustively tested by the files in this directory whose name match the pattern `prop-def-id-*.js`. Delete the redundant tests in favor of the more descriptively-named and more exhaustive alternatives. * Rename tests * Update test names to be more descriptive * Add tests for property descriptors of accessors * Add tests for runtime error during method dfn * Add test for observable iteration
