(BindingPattern, BindingElement, BindingTarget, Param) and cover grammar
for destructuring assignment (AssignmentPattern, AssignmentTarget).
Features: array/object patterns in let/const/var with defaults, holes,
rest elements, and nesting; function and arrow parameter destructuring;
destructuring assignment expressions ([a,b]=[b,a]); for-of/for-in with
destructured bindings; object shorthand properties ({x} means {x:x});
array elisions ([1,,3]). Includes 8 js262 fixtures and ~65 unit tests.
