	- Remove no longer needed noStrict flags. - Change tests to use propertyHelper.js for strict mode compatibility. - Add tests for return value of `delete` operator, e.g. `delete Array.prototype === false`. - Add non-writable tests for global NaN property. - Split some tests to run in strict mode. - Change tests with global `var length` declaration to use a different variable name for browser environments. - Merge duplicated tests symbol-data-property-configurable-non-strict and symbol-data-property-configurable-strict. - Merge duplicated tests symbol-data-property-writable-non-strict and symbol-data-property-writable-strict. - (And a small change in propertyHelper to reduce code duplication in function call.)
