e918748d88 improve collapsible value detection (#1638)

- but if assigned value is side-effect-free, no states can be modified, so it is safe to move

cf45e2f79b fixup for #1585 (#1589) 
As patched on `harmony`, `statement()` is the only user of `embed_tokens()` with a missing error branch.

Updated test case and match up with `harmony` to facilitate future merging.

f5cbe19b75 invert reduce_vars tracking flag (#1519) 
Modules like webpack and grunt-contrib-uglify still uses `ast.transform(compressor)` before `Compressor.compress(ast)` was introduced.

Workaround this compatibility issue by deactivating `reduce_vars` in such case.

Also fix use case with omitted `options` when calling `Compressor()`.

1e51586996 Support marking a call as pure 
A function call or IIFE with an immediately preceding comment
containing `@__PURE__` or `#__PURE__` is deemed to be a
side-effect-free pure function call and can potentially be
dropped.

Depends on `side_effects` option.

`[#@]__PURE__` hint will be removed from comment when pure
call is dropped.

98f330658f Generate source map data from normalized files 
If using `inSourceMap` this fix will ensure the copying of `sourcesContent` is based on potentially normalized `sources` values (https://github.com/mozilla/source-map/blob/master/lib/source-map-consumer.js#L304-L309).

For example `normalize` (https://github.com/mozilla/source-map/blob/master/lib/util.js#L80-L123) will rewrite `./dist/mySource.js` to `dist/mySource.js` in the target `_sources` of the `SourceMapConsumer`. As a result `orig_map.sourceContentFor(source, true);` would return `null` since the orginal `source` was no longer available in the consumer. By using the keys generating from the `SourceMapConsumer.constructor` consistency is ensured.

266ddd9639 fix uses_arguments handling (broken since 6605d15783) 
Using the symbol declaration tracking of UglifyJS doesn't make sense here
anyway, `arguments` always comes from something in the current scope.
