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.

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.

The `init` of the `ForStatement` is not a `BlockStatement` before it was
descended. The descend has to happen first, and *then* the actual

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.
