Previously, 'false & a == b' would actually execute the comparison and count it against the condition limit, while 'false & (a == b)' wouldn't. They behave the same now. mShortCircuit was only checked for the most potentially expensive operations (computing functions and getting variables), all the other operations on bogus values generated by this would be executed and the results ignored later. This probably doesn't noticeably improve performance, but it corrects how the condition limit is counted. Bug: T43693 Change-Id: Id1d5f577b14b6ae6d987ded12689788eb7922474
