feat(minifier): fold object constructor

[camchenry]

This will fold expressions like new Object() to {}. Based on the closure compiler tests: https://github.com/google/closure-compiler/blob/b7e380b6320a52ce7fbac0334ede00d6a8c92fad/test/com/google/javascript/jscomp/PeepholeSubstituteAlternateSyntaxTest.java#L78.

This is outside my usual area, so feedback is welcome.
