23* SUMMARY: Passing (RegExp object, flag) to RegExp() function.
24* This test arose from Bugzilla bug 61266. The ECMA3 section is:
25*
26* 15.10.3 The RegExp Constructor Called as a Function
27*
28*   15.10.3.1 RegExp(pattern, flags)
29*
30*   If pattern is an object R whose [[Class]] property is "RegExp"
31*   and flags is undefined, then return R unchanged.  Otherwise
32*   call the RegExp constructor (section 15.10.4.1),  passing it the
33*   pattern and flags arguments and return  the object constructed
34*   by that constructor.
35*
36*
37* The current test will check the first scenario outlined above:
38*
39*   "pattern" is itself a RegExp object R
40*   "flags" is undefined
41*
42* The flags parameter will be undefined in the sense of not being
43* provided. We check that RegExp(R) returns R  -
