*
*SUMMARY: Passing a RegExp object to a RegExp() constructor.
*This test arose from Bugzilla bug 61266. The ECMA3 section is:
*
* 15.10.4.1 new RegExp(pattern, flags)
*
* If pattern is an object R whose [[Class]] property is "RegExp" and
* flags is undefined, then let P be the pattern used to construct R
* and let F be the flags used to construct R. If pattern is an object R
* whose [[Class]] property is "RegExp" and flags is not undefined,
* then throw a TypeError exception. Otherwise, let P be the empty string
* if pattern is undefined and ToString(pattern) otherwise, and let F be
* the empty string if flags is undefined and ToString(flags) otherwise.
*
*
*The current test will check the first scenario outlined above:
*
* "pattern" is itself a RegExp object R
* "flags" is undefined
*
* We check that a new RegExp object obj2 defined from these parameters
* is morally the same as the original RegExp object obj1. Of course, they
* can't be equal as objects - so we check their enumerable properties...
*
* In this test, the initial RegExp object obj1 will not include a
* flag. The flags parameter for obj2 will be undefined in the sense
* of not being provided.
