ea6d1ea701 it's not safe to assume that property access is side-effect-free 
(getters/setters + various browser bugs will trigger side effects; also, an
exception is thrown when the expression is undefined)

42038fd67f Support input source map 
This is useful while compressing generated code; for example compressing JS
compiled by CoffeeScript (assuming you got a source map):

    uglifyjs2 --in-source-map generated.js.map \
              --source-map uglified.js.map \
              -o uglified.js

The above assumes you have a "generated.js.map" file which is the source
mapping between your CoffeeScript and the generated.js (compiled output from
CoffeeScript).  The name of the input file is not present in this example;
it will be fetched from the source map (but it can be passed manually too).

The output will be in "uglified.js" and the output map "uglified.js.map"
will actually map to the original CoffeeScript code, rather than to
generated.js.
