The output is now a tiny bit improved by sorting object properties
when inspecting the values that are compared with each other. That
reduces the overall diff for identical objects with a different

2) Short primitives do not use the diff anymore. Especially short

3) Improved error descriptions. It was not always clear what the

1) If simple assert is called in the very first line of a file and
it causes an error, it used to report the wrong code. The reason
is that the column that is reported is faulty. This is fixed by
subtracting the offset from now on in such cases.
2) The actual code read is now limited to the part that is actually
required to visualize the call site. All other code in e.g. minified
files will not cause a significant overhead anymore.
3) The number of allocations is now significantly lower than it used
to be. The buffer is reused until the correct line in the code is
found. In general the algorithm tries to safe operations where
possible.
4) The indentation is now corrected depending on where the statement
actually beginns.

One of the biggest downsides to the `assert.throws` API is that it
does not check for the error message in case that is used as second
argument. It will instead be used in case no error is thrown.
This improves the situation by checking the actual error message
against the provided one and throws an error in case they are
identical. It is very unlikely that the user wants to use that error
message as information instead of checking against that message.

Second, it is confusing. Is it a singleton/property or a getter? Which
should be expected? This can lead to subtle and hard-to-find bugs. (To
my knowledge, none have landed on master. But I also think it's only a
matter of time.)
Third, the abstraction is low-value in my opinion. What does it really
get us? A case could me made that it is without value at all.
Lastly, and this is minor, but the abstraction is wordier than not using
the abstraction. `common.noop` doesn't save anything over `() => {}`.
So, I propose removing it.

* 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.

In Node 7.x, calling `throw new assert.AssertionError()` resulted in a
TypeError.
In current master, the same call does not result in an error but, due to
the default option, it results in uninformative output ("undefined
undefined undefined").
This change removes the default argument, restoring a TypeError if there
is no argument. This also will restore our test coverage to 100%. (The
default argument is not tested in our current test suite.)

Using `assert.AssertionError()` without the `new` keyword results
in a non-intuitive error:

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.

Refactors _deepEqual and fixes a few code paths that lead to
behaviors contradicting what the doc says. Before this commit
certain types of objects (Buffers, Dates, etc.) are not checked
properly, and can get away with different prototypes AND different
enumerable owned properties because _deepEqual would jump to
premature conclusion for them.
Since we no longer follow CommonJS unit testing spec,
the checks for primitives and object prototypes are moved
forward for faster failure.
Improve regexp and float* array checks:
* Don't compare lastIndex of regexps, because they are not
enumerable, so according to the docs they should not be compared
* Compare flags of regexps instead of separate properties
* Use built-in tags to test for float* arrays instead of using
instanceof
Use full link to the archived GitHub repository.
Use util.objectToString for future improvements to that function
that makes sure the call won't be tampered with.
