Possible regression in RegExp.prototype.flags

[tanepiper]

I spotted this on http://node.green/#ES2015-misc-Proxy--internal--get--calls-RegExp-prototype-flags

It appears the tests for RegExp.prototype.flags have been failing but has been failing since 8.3.0

It's an issue with the test case because it doesn't account for the possibility of additional flags existing, such as dotAll which is currently available in V8.
