[acl] Hoisted global variables in with-clause always need read access

[t2ym]

[acl] Hoisted global variables in with-clause always need read access

Root Cause

• Unused read access is attached in the hoisted var declarations

Reproducible Code

• Original

with ({}) {
  var v = 1;
}

• Hooked (Pseudo)

$hook$.global('v', 'var)[_c_[0]]; // unnecessary read access to the variable with property access
with (__with__) {
  __hook__('w=', __with__, ['v', 1, (p) => v = p, v], _c_[0], false); // write access
}

Fix

• Omit unnecessary property access

$hook$.global('v', 'var'); // equivalent to Object.defineProperty(window, 'v', { value: undefined })
with (__with__) {
  __hook__('w=', __with__, ['v', 1, (p) => v = p, v], _c_[0], false); // write access
}
