Let me see if I get this right...

You are changing the behavior of opaque types with respect to
__builtin_types_compatible_p?  If so, we don't really care about a
change in this functionality because SPE uses opaque types but does
NOT use __builtin_types_compatible_p.  So, nothing changes.

OTOH, if you change the behavior of opaque types wrt
__builtin_types_compatible_p, this doesn't affect AltiVec either
because AltiVec uses __builtin_types_compatible_p but does NOT use
opaque types.

Agreed?

If so, why the change at all.  What code would it affect?
