- Remove silly empty anonymous blocks left over from drop_unused
- AST_Toplevel now gets to call drop_unused too, since block-scoped variables aren't global!

Fix compressing conditionals
...
Only transform foo() ? EXP(x) : EXP(y) into EXP(foo() ? x : y) if EXP has no
side effects.

Added expect_exact for testing the OutputStream
...
This works almost exactly like `expect`, except that you pass a literal string
of which the result is compared with the generated output.

Fix compression of conditionals
...
Don't move the condition on the right side of an assignment when
the left side may have side effects.

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".

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.

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.

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.
