* Remove needless RegExp flag
In fixed case, `/g` flag is needless in the boolean context.
* Remove needless RegExp capturing
Use non-capturing grouping or remove capturing completely when:
* capturing is useless per se, e.g. in test() check;
* captured groups are not used afterward at all;
* some of the later captured groups are not used afterward.
* Use test, not match/exec in boolean context
match() and exec() return a complicated object,
unneeded in a boolean context.
* Do not needlessly repeat RegExp creation
This commit takes RegExp creation out of cycles and other repetitions.
As long as the RegExp does not use /g flag and match indices,
we are safe here.
In tests, this fix hardly gives a significant performance gain,
but it increases clarity and maintainability,
reassuring some RegExps to be identical.
RegExp in functions are not taken out of their functions:
while these functions are called many times
and their RegExps are recreated with each call,
the performance gain in test cases
does not seem to be worth decreasing function self-dependency.

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.

One downside to `common.expectsError()` is that it increases the
abstractions people have to learn about in order to work with even
simple tests. Whereas before, all they had to know about is
`assert.throws()`, now they have to *also* know about
`common.expectsError()`. This is very different (IMO) from
`common.mustCall()` in that the latter has an intuitively understandable
name, accepts arguments as one would expect, and (in most cases) doesn't
actually require reading documentation or code to figure out what it's
doing. With `common.expectsError()`, there's a fair bit of magic. Like,
it's not obvious what the first argument would be. Or the second. Or the
third. You just have to know.
This PR changes the arguments accepted by `common.expectsError()` to a
single settings object. Someone coming across this has a hope of
understanding what's going on without reading source or docs:
```js
const validatorFunction = common.expectsError({code: 'ELOOP',
type: Error,
message: 'foo'});
```
This, by comparison, is harder to grok:
```js
const validatorFunction = common.expectsError('ELOOP',
Error,
'foo');
```
And this is especially wat-inducing:
```js
common.expectsError(undefined, undefined, 'looped doodad found');
```
It's likely that only people who work with tests frequently can be
expected to remember the three arguments and their order. By comparison,
remembering that the error code is `code` and the message is `message`
might be manageable.
