Ensure that we cannot get any dangling pointers into code that
has been purged. This is done by a two phase purge. At first
phase all fun entries pointing into the code to purge are marked
for purge. All processes trying to call these funs will be suspended
and by this we avoid getting new direct references into the code.
When all processes has been checked, these processes are resumed.
The new purge strategy now also completely ignore the existence of
indirect references to the code (funs). If such exist, they will
cause bad fun exceptions to the caller, but will not prevent a
soft purge or cause a kill of a process having such live references
during a hard purge. This since it is impossible to give any
guarantees that no processes in the system have such indirect
references. Even when the system is completely clean from such
references, new ones can appear via distribution and/or disk.

Besides using two words for 'milliseconds' et. al. they are
also changed from plural to singular.

erts: Align ErtsThrPrgrLaterOp when free'ing tracer
|
|
On Sparc all structs with a double word element in are assumed
to be allocated on a two word boundary. So we have to make sure
that the ErtsThrPrgrLaterOp * points to 8 / 16 byte aligned memory.
As it only costs one word I've done it on all architectures in case
some unknown other arch also needs this.

check_process_code: Sweep HiPE stack for literals
|

We need to use an initial hash seed for each map pair, i.e. the
hash value. The hash value is reset to the seed for each pair instead
of setting the seed to zero.
If we don't, no additional entropy is given to the system and the
hash collision resolution in maps:from_list/1 would fail.

This type of statistics is now available through the microstate

This is needed in order for the heap to never contain
any pointers to invalid memory. This is good for performance
and debugging reasons.

in 'set' with 'write_concurrency'
when inserting default object causes table to grow
and the bucket to split is protected by same lock as the key.

Symptom: VM abort "Overrun stack and heap"
Problem: The temporary bignum created in buffer tmp_big[] will be
part of the GC initiated by TestHeapPreserve, but its size is not
included which can cause the GC to overflow if very unlucky.
Solution: Do not include tmp_big in the GC.

|
We have to do an extra check if the return_to trace is enabled here
as it may have been cleared by the bif after the flags where
created by the call_trace.
