Attached patch PatchSplinter Review
This patch just passes the script/pc to the stub. The micro-benchmark below drops from 503 ms to 209 ms, about as fast as JM+TI. Bug 612993, where I noticed this, improves from 22 ms to 19.3 ms.

function test() {
    var s1 = "foo";
    var o = {foo: 0};

    for (var i=0; i<2000000; i++) {
        o[s1]++;
    }
    print(o.foo);
}
var t = new Date;
test();
print(new Date - t);
