[issue6690] BUILD_SET followed by COMPARE_OP (in) can be optimized if all items are consts

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

No, you can't rely on the repr of a frozenset with multiple items. You should find another way of testing (if you are brave you could match the "frozenset(...)" with a regex and eval() it).

Some comments on the patch:
- there's a line or two in peephole.c which seems to use spaces for indentation; please always use tabs (for this file anyway)
- instead of `self.assertTrue(X in Y)`, you can use `self.assertIn(X, Y)` (and `self.assertNotIn(X, Y)` for the negation)
