bb0a762d12 Only allow identifier start characters at the beginning of identifiers. 
Without this fix, the following source:

   x = {"\u200c": 42};

would incorrectly be converted into a quoteless key. But while \u200c is allowed
to be in identifiers, it cannot be at the beginning, as per ES5.

(For example, the SockJS client library doesn't work under uglify starting with
d9ad3c7c.)

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.

the return value is important or discarded)

Revert "added option for dropping unused params"

(turns out we already had the `unused` option for this.)

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.
