OR and AND of EnumValues should be supported and return ints

[Barry Warsaw]

From python-ideas:

class Flags(Enum):
    beautiful = 1
    fast = 2
    elegant = 4
    wonderful = 8

>>> Flags.fast | Flags.elegant
6

Returning an int from such operations is the only sensible interpretation.

I prefer something like

 >>> TypeFlag.HAS_GC | TypeFlag.INT_SUBCLASS
TypeFlag.HAS_GC|INT_SUBCLASS

This would be nice to have, but only for IntEnum values. Still, I'm un-milestoning it for the 3.4 release.

Of course, since IntEnums let you do all the logical operations you can already do with ints, we're just talking about having a nicer repr here. The added complexity isn't worth it.
