Defer lookup of opfamily and input type of a of a user specified opclass until the optimizer selects among available unique indexes; and store the opclass in the parse analyzed tree instead. The primary reason for doing this is that for rule deparsing it's easier to use the opclass than the previous representation. While at it also rename a variable in the inference code to better fit it's purpose. This is separate from the actual fixes for deparsing to make review easier.
