*
* SUMMARY: Passing (RegExp object, flag) to RegExp() function.
* This test arose from Bugzilla bug 61266. The ECMA3 section is:
*
* 15.10.3 The RegExp Constructor Called as a Function
*
* 15.10.3.1 RegExp(pattern, flags)
*
* If pattern is an object R whose [[Class]] property is "RegExp"
* and flags is undefined, then return R unchanged. Otherwise
* call the RegExp constructor (section 15.10.4.1), passing it the
* pattern and flags arguments and return the object constructed
* by that constructor.
*
*
* The current test will check the first scenario outlined above:
*
* "pattern" is itself a RegExp object R
* "flags" is undefined
*
* The flags parameter will be undefined in the sense of not being
* provided. We check that RegExp(R) returns R -
