In case of a failure it will now throw an `AssertionError` instead

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.
5) It is now possible to handle `.call()` and `.apply()` properly.
6) The user defined function name will now always be used instead of

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.
