If there is a frequently taken branch dominated by a guard, and its condition is available
at the point of the guard, we can widen guard with condition of this branch and convert
the branch into unconditional:
guard(cond1)
if (cond2) {
// taken in 99.9% cases
// do something
} else {
// do something else
}
Converts to
guard(cond1 && cond2)
// do something
