LibJS: Hook up Regex<ECMA262> to RegExpObject and implement `test()'

Browse source 
This makes RegExpObject compile and store a Regex<ECMA262>, adds
all flag-related properties, and implements `RegExpPrototype.test()`
(complete with 'lastIndex' support) :^)
It should be noted that this only implements `test()' using the builtin
`exec()'.
