avoid os:cmd as it treats stderr different on windows.

On a computer which is fast, but with timers with low resolution,
the measured time for an empty queue could be zero, which could
cause the test case to fail.
Add a calibration function to scale up the amount the amount of
work so that the measured time will not be lower than 50 ms.

* bjorn/compiler/binary-comprehensions/OTP-13289:
Generalize bit string comprehensions
|

The expression in a bit string comprehension is limited to a
literal bit string expression. That is, the following code
is legal:
<< <<X>> || X <- List >>
but not this code:
<< foo(X) || X <- List >>
The limitation is annoying. For one thing, tools that transform
the abstract format must be careful not to produce code such as:
<< begin
%% Some instrumentation code.
<<X>>
end || X <- List >>
One reason for the limitation could be that we'll get
reduce/reduce conflicts if we try to allow an arbitrary
expression in a bit string comprehension:
binary_comprehension -> '<<' expr '||' lc_exprs '>>' :
{bc,?anno('$1'),'$2','$4'}.
Unfortunately, there does not seem to be an easy way to work
around that problem. The best we can do is to allow 'expr_max'
expressions (as in the binary syntax):
binary_comprehension -> '<<' expr_max '||' lc_exprs '>>' :
{bc,?anno('$1'),'$2','$4'}.
That will work, but functions calls must be enclosed in
parentheses:
<< (foo(X)) || X <- List >>

Removing events from the internal queues is not necessary with
the choosen semantics of the event queue vs. hibernate.
In an early implementation it was possible by combining
hibernate with e.g. postpone to get an event in the queue
that you would not see before processing the postponed event,
and therefore should you decide to cancel a timer it was
essential to be able to remove that unseen event from the queue.
With the choosen semantics you will have to postpone or generate
an event for it to be in the event queue, and if you e.g. postpone
a timeout event and then cancel the timer it is your mistake.
You have seen the event and should know better than to try to
cancel the timer.
So, the actions: remove_event, cancel_timer, demonitor and unlink
are now removed.
There have also been some cleanup of the timer handling code.

The reason is that the module is not used, and that we se no obvious
use case for it.

Forms with record field types created before OTP 19.0 are replaced by
well-formed record forms holding the type information.
Tools reading the 'abstract_code' chunk can rely on the returned forms
being well-formed, that is, there are no badly formed 'type' attribute
forms.
