Refactor predicate_{implied,refuted}_by_simple_clause.

Put the node-type-dependent operations into switches on nodeTag.
This should ease addition of new proof rules for other expression
node types.  There is no functional change, although some tests
are made in a different order than before.

Also, add a couple of new cross-checks in test_predtest.c.
