Doug Gregor c0917c90d2 [Constraint solver] Revert the "common type" optimization.
The "common type" optimization isn't really buying us anything at this
point, because we're not able to make much use of the common structure
often enough. Revert the "common type" optimization for now... I'll
bring it back when there's enough optimization infrastructure around
it to make it compelling.
