A DESCRIPTION OF THE PROBLEM :
For the following JavaScript (which is a minimal repro from from goog Closure integer manipulation code):

! function() {
    function t(t, i) {
        for (var $ = !0, r = t.length - 1; r >= 0; r--) {
              $ && e == i
        }
    }
    function i(i) {
        return r = new t(0)
    } {
        i(0)
    }
}();

jjs will fail to generate bytecode

REGRESSION. Last worked in version 8u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the file in jjs:

$JAVA_HOME/bin/jjs file.js

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect no output
ACTUAL -
Failure to generate bytecode
