- refactor `screw_ie8` to `ie8`
- compact `sourceMap` options
- more stringent verification on input `options`
- toplevel shorthands
- `ie8`
- `keep_fnames`
- `toplevel`
- deprecated `fromString` in `minify()`
- `minify()` no longer handles any `fs` operations
- unify order of operations for `mangle_properties()` on CLI & API
- `bin/uglifyjs` used to `mangle_properties()` before even `Compressor`
- `minify()` used to `mangle_properties()` after `Compressor` but before `mangle_names()`
- both will now do `Compressor`, `mangle_names()` then `mangle_properties()`
- `options.parse` / `--parse` for parser options beyond `bare_returns`

That particular version of Node.js has messed up error messages, so provide a version-specific workaround.
Also fixed an formatting issue which would cause `expect_stdout` to fail if error message contains excerpts of input.
Apply `expect_stdout` to more applicable tests.
- omitting trailing semi-colon in do-while breaks non-browser parser, e.g. uglify-js 1.x
- trailing semi-colon only breaks IE8 if followed by `else` or `while`
- always use braces in do-while body to workaround 2nd case with no size loss in compression
fixes#1568
for(...; x; ...) if (y) break; → for(...; x&&!y; ...);
similarly for `while` and some combinations (i.e. the `break` appears in the
`else` clause, etc.)
