transformObjectKeys and single statement braceless blocks

[kluns]

Using transformObjectKeys converts some single statement assignments into multiple statements. When this occurs in a single statement if block without braces no braces are added to keep the full assignment in the if block. This can cause undefined object errors.

Expected Behavior

This code should not have errors when the condition is false:

function hi() {
  var i = 1;
  tstArray = new Array(0);
  if (i === 0)
    tstArray[0] = {state1: "on", state2: "off"};
  i += 1;
}
hi();

Current Behavior

function hi() {
    var _0x106765 = 0x1;
    tstArray = new Array(0x0);
    if (_0x106765 === 0x0)
        tstArray[0x0] = {};
    tstArray[0x0]['state1'] = 'on';
    tstArray[0x0]['state2'] = 'off';
    _0x106765 += 0x1;
}
hi();
