61e850ceb5 Clean up unit test breakage 
In 992b6b9fcc unit test broke (which I missed). This was due to undeclared variables not being side-effects free.

However, since they're really not side-effect free, just declare them in the test cases.

c75f5a1fd8 Fix #597 
NaN and Infinity were replaced in the output generation, instead of
during compression. This could lead to results where `1/0` was inserted
without parens leading to invalid output.

The nodes are replaced in the compression step now, and the output
generation returns their regular names. This should not be a problem,
since they're already only constructed from the original name.
