8b71c6559b Mark vars with /** @const */ pragma as consts so they can be eliminated. 
Fixes older browser support for consts and allows more flexibility
in dead code removal.

Caught an error in #847 as well - `output` wasn't passed anywhere which led to an exception. `options` was available though.

ecfd881ac6 Keep unused function arguments by default 
Discarding unused function arguments affects function.length, which can lead
to some hard to debug issues.  This optimization is now done only in "unsafe
mode".

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.

992b6b9fcc Fix invalid removal of left side in && and || compression 
See #637. This does not produce the optimal result, but it does prevent the removal of non-side-effect-free code.

605362f89d Drop all console statements properly 
Because the base reference can be an member expression as well, we have to dig a bit deeper to find the leftmost base reference.

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.
