a5b60217ce Fix compressing conditionals
Only transform foo() ? EXP(x) : EXP(y) into EXP(foo() ? x : y) if EXP has no
side effects.

de58b0289d 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.

18c63ff3d8 Fix compression of conditionals
Don't move the condition on the right side of an assignment when
the left side may have side effects.

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.

eab99a1c3d Better fix for #343
We can in fact lift sequences, but only if the operation is assignment and
the left-hand side has no side effects nor property access -- that should
guarantee that whatever we place before it cannot affect the sense of the
assignment.

Dropped contrived test case (too hard to support it now), added a more
meaningful one.

118105db43 Add an exit code to the test suite
By adding the exit code 1 (or any other non-zero exit code) `npm test`
will know the tests didn't perform correctly. This way it's easier to
know if pull requests are good or bad.

037199bfe2 Actually let's move away those monsters from the evaluate function
ev() should do a single thing — evaluate constant expressions.  if that's
not possible, just return the original node.  it's not the best place for
partial evaluation there, instead doing it in the compress functions.

b1febde3e9 Fix output for arrays whose last element is a hole: [1,,]
1529ab96 started to do this (by considering holes to be separate from
"undefined") but it still converted
   [1,,]    (length 2, last element hole, trailing comma)
to
   [1,]     (length 1, trailing comma)

Unfortunately the test suite doesn't really make this clear: the new test here
passes with or without this patch because run-tests.js beautifys the expected
output (in "make_code"), which does the incorrect transformation! If you make
some manual change to arrays.js to make the test fail and see the INPUT and
OUTPUT, then you can see that without this fix, [1,,] -> [1,], and with this fix
it stays [1,,].
