634f231b78 First class block scope 
- Make let, const, and class symbols be declared in a block scope.
- Piggy back on existing catch symbol implementation to get block-aware mangling working
- Make sure unused block-scoped declarations can be dropped
- Don't eliminate a block if it has a block-scoped declaration
- 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!
- Don't consider block declarations global

61e850ceb5 Clean up unit test breakage

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.

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.

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,,].
