Provide rename location for extractMethod in presence of writes

[ghost]

TypeScript Version: master

Code

/// <reference path='fourslash.ts' />

////function foo() {
////    var i = 10;
////    /*a*/i++/*b*/;
////}

goTo.select("a", "b");
edit.applyRefactor({
    refactorName: "Extract Method",
    actionName: "scope_1",
    actionDescription: "Extract function into global scope",
    newContent:
`function foo() {
    var i = 10;
    i = /*RENAME*/newFunction(i);
}
function newFunction(i: number) {
    i++;
    return i;
}
`
});

Expected behavior:

Get rename location.

Actual behavior:

Get nothing.

in the light of the offline discussion we had, i do not think we need this. will leave it open for now. please close it when we have the final implementation for rename locations.
