62bda71c85 Fix parens for AST_Undefined 
Do the same as for AST_Unary, since we output undefined as `void 0`.

7bf59b5bcd Actually, even better. #475 
- also handle x = + ++y, x = - --y;
- don't use parens, a space suffices.

c5ed2292bf Fix parsing setters/getters (allow keywords for name). 
The "key" property was always "set" or "get", which didn't make much sense.
Now it'll be the actual name of the setter/getter (AST_Node), and the
AST_Accessor object itself, which represents the function, won't store any
name.

ed80b4a534 Move support for negate_iife in the compressor, rather than code generator 
(the code generator doesn't maintain enough context to know whether
the return value is important or discarded)

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,,].

f29f07aabd Escape null characters as \x00 
Since \0 might be mistakenly interpreted as octal if followed by a
number and using literal null is in some cases interpreted as end of
string, escape null as \x00.

1529ab965a Fix output for arrays containing undefined values. 
1b6bcca7 was a first attempt at this. That commit made Uglify stop replacing
holes with undefined, but instead it started replacing undefined with
holes. This is slightly problematic, because there is a difference between a
hole and an undefined value. More problematically, it changed [1,undefined] to
[1,] which generally doesn't even parse as a hole (just as a trailing comma), so
it didn't even preserve the length of the array!

Instead, parse holes as their own special AST node which prints invisibly.
