Replaced the monitor (to the tc runner process) with
a link. The point is that if the test case "stalls",
the ts (ct) framework shall kill it (with the test case
process).

Without this I wasn't able to compile the debug emulator, the compilation
would fail with "section attribute is specified on redeclared variable" errors.

The function used by "all" the agent test cases to
actually run the operations have been improved.
There was previously very little monitoring of the
result. Have added some (minor) checks, both before
trying to running the test case, and "during".
Such as, is the node we attempt to use actually alive.
Then, when we spawn the test case runner process on
the (remote) node, make it report back before trying
to run the actuall test case (so we know that the spawn
worked.
Also added a monitor of the process, so that we will
detect fatal errors.

A repeated test could be optimized away. Example:
bar(A) ->
if is_bitstring(A) ->
if is_binary(A) ->
binary;
true ->
bitstring
end;
true ->
other
end.
In the example, the `is_binary/1` test would be optimized away,
basically turning the example into:
bar(A) ->
if is_bitstring(A) ->
bitstring;
true ->
other
end.
Thanks user Marcus Kruse in the Elixir forum for noticing this bug.

The compiler could crash in the beam_ssa_dead pass while compiling
complex nested `case` expressions. See the added test case for an
example and explanation.

In https://bugs.gentoo.org/686786 gcc-9.1.0 exposed
a bug in erts/configure: if compiler does not support
PGO flags the configure process calls 'yes = yes'
(indefinite loop) instead of 'test yes = yes'.
The change does not fix gcc-9.1.0 PGO detection but
fixes ./configure termination.

The following Core Erlang code could not be loaded:

The type optimizer pass (`beam_ssa_type`) could make unsafe
negative inferences. That is, incorrectly infer that a variable
could *not* have a particular type.
This bug was found when adding another optimization. It is not
clear how write a failing test case without that added optimization.

When catching an exception re-throwing with a changed

if the exception got caught and rethrown in (for example)
an after block:
