23*SUMMARY: Passing a RegExp object to a RegExp() constructor.
24*This test arose from Bugzilla bug 61266. The ECMA3 section is:
25*
26*  15.10.4.1 new RegExp(pattern, flags)
27*
28*  If pattern is an object R whose [[Class]] property is "RegExp" and
29*  flags is undefined, then let P be the pattern used to construct R
30*  and let F be the flags used to construct R. If pattern is an object R
31*  whose [[Class]] property is "RegExp" and flags is not undefined,
32*  then throw a TypeError exception. Otherwise, let P be the empty string
33*  if pattern is undefined and ToString(pattern) otherwise, and let F be
34*  the empty string if flags is undefined and ToString(flags) otherwise.
35*
36*
37*The current test will check the second scenario outlined above:
38*
39*   "pattern" is itself a RegExp object R
40*   "flags" is NOT undefined
41*
42* This should throw an exception ... we test for this.
