Loads/stores with non-escaping arrays can be disambiguated from loads/store
with unknown identity.
This enables better load elimination for non-escaping arrays.
For example in the following code:
test() {
var a = new List(1);
var b = new List(1);
a[0] = 42;
b[0] = 43;
return a[0] + b[0];
}
we can now eliminate both loads a[0] and b[0] where before all stores to [0] were
considered to interfere with each other..
