+- `hoist_props` (default: `true`) -- hoist properties from constant object and
array literals into regular variables subject to a set of constraints. For example:
`var o={p:1, q:2}; f(o.p, o.q);` is converted to `f(1, 2);`. Note: `hoist_props`
works best with `mangle` enabled, the `compress` option `passes` set to `2` or higher,
`foo` is certain to not throw, i.e. not `null` or `undefined`.
