Microsoft Edge: Chakra: JIT: Incorrect bounds calculation(CVE-2018-0769)

Let's start with comments in the "GlobOpt::TrackIntSpecializedAddSubConstant" method. // Track bounds for add or sub with a constant. For instance, consider b = a + 2. The value of 'b' should track // that it is equal to the value of 'a' + 2. That part has been done above. Similarly, the value of...
