Added an implicit unconstrainedEquality override to LegacyTripleEquals. This was just a bug that it was missing, but it 
meant that for 2.9 I had to comment out more tests.

Made the methods in EqualityConstraints abstract. Added .for210 copies of the tests that
compiler under 2.10 but not 2.9 to make it easier to run them in 2.10.
