Lint Suboptimal Expression Order

[llogiq]

(This one is nicked from fb-contrib). Lint expressions of the kind

(method)call &&/|| (no method call) {==, !=} (no method call)

e.g. potentially_expensive_check() && a == b

And suggest to reorder the subexpressions to possibly improve performance. Note that this may change behavior if potentially_expensive_check() has side effects.
