[Bug c++/38064] [c++0x] operator== doesn't work for enum classes

With unscoped enums the similar code works because cp_build_binary_op applies
the default integral promotions to the enums, and winds up comparing two int
values.  The promotions are not applied to scoped enums because
default_conversion checks INTEGRAL_OR_UNSCOPED_ENUMERATION_TYPE_P.  I would
guess that this would work if several checks in cp_build_binary_op also checked
for ENUMERAL_TYPE in cases where they currently check for INTEGER_TYPE.  But I
haven't tried to read the standard to understand where the right fix is.
