This enables a --loader flag for Node, which can provide custom
"resolve" and "dynamicInstantiate" methods for custom ES module
loading.
In the process, module providers have been converted from classes
into functions and the module APIs have been made to pass URL strings
over objects.

Enablie a lint rule to require `===` and `!==` instead of `==` and `!=`
except in some well-defined cases:
* comparing against `null` as a shorthand for also checking for
`undefined`
* comparing the result of `typeof`
* comparing literal values
In cases where `==` or `!=` are being used as optimizations, use an
ESLint comment to disable the `eqeqeq` rule for that line explicitly. I
rather like this because it's a signal that the usage is intentional and
not a mistake.

The second argument to "assert.throws" is usually a validation RegExp or
function for the thrown error. However, the function also accepts a
string and in this case it is interpreted as a message for the
AssertionError and not used for validation. It is common for people to
forget this and pass a validation string by mistake.
This new rule checks that we never pass a string literal as a second argument
to "assert.throws". Additionally, there is an option to enforce the
function to be called with at least two arguments. It is currently off
because we have many tests that do not comply with this rule.
