The previous test amount could take up to 3 hours to finish!

When running multiple valgrinds on the same machine we want to
attempt to make sure that they do not end up on the same core.

Before this change erts used to crash dump and then abort, but a
crash dump is not really usefull at this point and it caused all
sort of lock problems when crash dumping that early in the system
boot, so now it is changed to only dump core instead.
Also in the process I cleaned up some the code so that it does
not to a lot of things that are not needed.

erlexec: Fix argument separation when mixing env flags
|
|
Example:
export ERL_AFLAGS=-test
erl dummy_param
In the above example, the dummy_param would be interpreted
as an argument to -test, and not as a separate argument as
it should.

Seems the right thing to do as the compiled code is not necessarily
executed by a single CPU thread.
Only warning if old gcc and will work as good/bad as it did before.

ETS ordered_set: Improvements to the CA tree implementation
|
|
This commit only affects the implementation of ETS `ordered_set`
tables with the `write_concurrency` option enabled. Such tables are
implemented with a data structure that is called the contention
adapting search tree (CA tree). This commit introduces the following
changes:
* This commit causes a join to be triggered in one randomly selected
base node in about one of 1000 read unlock calls for base node
locks. No such joins happened before this commit. Before this
commit, operations that only acquired looks in read-mode never
triggered any contention adaptation. Therefore, the CA tree could
get stuck in a sub-optimal state in certain scenarios. This could
happen, for example, when a CA tree is first populated with parallel
inserts (which will cause splits of base nodes) and then only
read-only operations are applied to the data structure. Benchmark
results from the
`ets_SUITE:lookup_catree_par_vs_seq_init_benchmark/0` benchmark
function (which is included in this commit) shows that this change
can improve the throughput of the CA tree in the scenario described
above.
* Read-only operations will now also increase values of statistics
counters when they detect that they need to wait for other
operations. Only write operation changed statistics counters before
this commit. This improves the statistics that the adaptation
heuristics is based on.
* Additionally, this commit adds an upper and lower limit to the
contention statistics variables in the base nodes. Such limits did
not exist before this commit. This should, for example, make the CA
tree more responsive to contention after long periods of low
contention.
