AssertionError class is moved to interna/error
in reference to the TODO in assert.js. This was
suggested to get rid of the cyclic dependency
between assert.js and internal/error.js

Using `assert.AssertionError()` without the `new` keyword results
in a non-intuitive error:
```js
> assert.AssertionError({})
TypeError: Cannot assign to read only property 'name' of function 'function ok(value, message) {
if (!value) fail(value, true, message, '==', assert.ok);
}'

The `assert.AssertionError()` can only be used correctly with `new`,
so this converts it into a proper ES6 class that will give an
appropriate error message.
This also associates the appropriate internal/errors code with all
`assert.AssertionError` instances and updates the appropriate test
cases.

The file no longer works after the removal of the --debug/--debug-brk
switches in commit 47f8f74 ("src: remove support for --debug".)
This commit also removes several tests that still referenced the
old debugger but were either unit-testing its internals or passing
for the wrong reason (like expecting an operation to fail, which
it did because the debugger is gone.)

Commit c5b07d4 ("lib: fix beforeExit not working with -e") runs the
to-be-evaluated code at a later time than before because it switches
from `process.nextTick()` to `setImmediate()`.
It affects `-e 'process.on("message", ...)'` because there is now a
larger time gap between startup and attaching the event listener,
increasing the chances of missing early messages. I'm reasonably
sure `process.nextTick()` was also susceptible to that, only less
pronounced.
Avoid the problem altogether by evaluating the code synchronously.
Harmonizes the logic with `Module.runMain()` from lib/module.js
which also calls `process._tickCallback()` afterwards.

There are places in the code base where setTimeout() or
setInterval() are called with just a callback and no duration/interval.
The timers module will use a value of `1` in that situation.
An unspecified duration or interval can be confusing. Did the original
author forget to provide a value? Did they intend to use setImmediate()
or process.nextTick() instead of setTimeout()? And so on.
This change provides a duration or interval of `1` to all calls in the
codebase where it is missing. `parallel/test-timers.js` still tests the
situation where `setTimeout()` and `setInterval()` are called with
`undefined` and other non-numeric values for the duration/interval.

Commit 93a44d5 ("src: fix deferred events not working with -e") defers
evaluation of the script to the next tick.
A side effect of that change is that 'beforeExit' listeners run before
the actual script. 'beforeExit' is emitted when the event loop is
empty but process.nextTick() does not ref the event loop.
Fix that by using setImmediate(). Because it is implemented in terms
of a uv_check_t handle, it interacts with the event loop properly.

This commit improves timers performance by making functions

This commit also makes setTimeout/Interval argument handling

- Adds the `breakEvalOnSigint` option to `vm.runIn(This)Context`.
This uses a watchdog thread to wait for SIGINT and generally works
just like the existing `timeout` option.
- Adds a method to the existing timer-based watchdog to check if it
stopped regularly or by running into the timeout. This is used to
tell a SIGINT abort from a timer-based one.
- Adds (internal) `process._{start,stop}SigintWatchdog` methods to
start/stop the watchdog thread used by the above option manually.
This will be used in the REPL to set up SIGINT handling before
entering terminal raw mode, so that there is no time window in
which Ctrl+C fully aborts the process.

Don't cache the exported values of fully uninitialized builtins.
This works by adding an additional `loading` flag that is only
active during initial loading of an internal module and checking
that either the module is fully loaded or is in that state before
using its cached value.
This has the effect that builtins modules which could not be loaded
(e.g. because compilation failed due to missing stack space) can be
loaded at a later point.

However, when user code catches an error, it has no way to
access the arrow message. This commit changes the behavior of
displayErrors to mean "decorate the error stack if an error
