In a previous commit, the loader implementation was modified to be
protected against most prototype pollution, but was kept vulnerable to
`Array.prototype` pollution. This commit fixes that, the tradeoff is
that it modifies the `ESMLoader.prototype.import` return type from an
`Array` to an array-like object.

These changes no-duplicate-require.js so that it doesn't use an
assignment in a conditional, which can be easy to misread as a
comparison rather than an assignment. It also means we change a do/while
(which we don't use much in our code) to the much more common while
construct.

The fixer for non-ascii-character does not typidally do the right thing.
It removes the entire node, not the offending character. I discovered
this when it removed the entire contents of a file and I wasn't sure
which auto-fix rule was doing it.
This commit adds a minimal test for the rule. The tests require that
auto-fix results be supplied, so if someone wants to re-add auto-fixing
to the rule, we'll have tests that it does the right thing.

Iterating over arrays should be avoided because it relies on
user-mutable global methods (`Array.prototype[Symbol.iterator]`
and `%ArrayIteratorPrototype%.next`), we should instead use
other alternatives. This commit adds a rule that disallow
array destructuring syntax in favor of object destructuring syntax.
Note that you can ignore this rule if you are using
the array destructuring syntax over a safe iterable, or
actually want to iterate over a user-provided object.

I added a new custom ESLint rule to fix these problems.
We have a lot of replaceable codes with primordials.
Accessing built-in objects is restricted by existing rule
(no-restricted-globals), but accessing property in the built-in objects
is not restricted right now. We manually review codes that can be
replaced by primordials, but there's a lot of code that actually needs
to be fixed. We have often made pull requests to replace the primordials
with.
Restrict accessing global built-in objects such as `Promise`.
Restrict calling static methods such as `Array.from` or `Symbol.for`.
Don't restrict prototype methods to prevent false-positive.
