The types named_curve/0 consist of many
options and may also change with time. Since they are not
exported, users must either repeat and maintain their specs,
or use a general type like any() if they want to refer
to them.

If the log file name was given as a relative path, logger_std_h
erroneously tried to create a new file in a new location if the
current working directory of the node was changed. This is now
corrected.

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.

Make erlang:phash2/1 and erlang:phash2/2 yield

The erlang:phash2 functions did not yield even if the input was very
large and a call to one of the functions did only consume a single
reduction. This commit fixes these problems.

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:
'f'/1 = fun (_1) ->
case <_1> of
<~{'foo':='foo'}~> when 'true' ->
_1
end
Loading would fail with the following message:
beam/beam_load.c(2314): Error loading function example:f/1: op i_get_map_element_hash p x a u x:

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.
