This is needed with the new poll-thread implementation
as now closed fd's in the pollset will be triggered much
faster than before.

We start the port in the started process in order
to get the messages in the correct place and also
so that unloading the port driver does not kill the
test process.

As a preparation for potentially improving packing in the future,
we will need to make sure that packable types have a defined maximum
size.
The packer algorithm assumes that two 'I' operands can be packed
into one 64-bit word, but there are instructions that use an 'I'
operand to store a pointer. It only works because those instructions
are not packed for other reasons.
Introduce the 'W' type and use it for operands that don't fit in
32 bits.

The instruction put_map_assoc/5 (used for updating a map) has a
failure operand, but it can't actually fail provided that its "map"
argument is a map.
The following code:
M#{key=>value}.
will be compiled to:
{test,is_map,{f,3},[{x,0}]}.
{line,[...]}.
{put_map_assoc,{f,0},{x,0},{x,0},1,{list,[{atom,key},{atom,value}]}}.
return.
{label,3}.
%% Code that produces a 'badmap' exception follows.
Because of the is_map instruction, {x,0} always contains a map when
the put_map_assoc instruction is executed. Therefore we can remove
the failure operand. That will save one word, and also eliminate
two tests at run-time.
The only problem is that the compiler in OTP 17 did not emit a
is_map instruction before the put_map_assoc instruction. Therefore,
we must add an instruction that tests for a map if the code was
compiled with the OTP 17 compiler.
Unfortunately, there is no safe and relatively easy way to known that
the OTP 17 compiler was used, so we will check whether a compiler
before OTP 20 was used. OTP 20 introduced a new chunk type for atoms,
which is trivial to check.

Also, fix cleaning up the OS environment setting modified by this test
case to prevent problems with later test cases using the echo_drv too.

'0 bsl 134217728' would fail with a system limit exception on a 32-bit
BEAM machine, but not on a 64-bit BEAM machine. Smaller values
on the right would always work.
Make erlang:bsl(0, BigNumber) always return 0 to make for consistency.
(The previous commit accidentally did that change for
'0 bsl BigNumber'.)

This fixes the following bug:
A = <<0:((1 bsl 32)-8)>>,
B = <<2, 3>>.
B =:= <<A/binary,1,B/binary>>. %% Evaluated to true...
