2016-08-12erts: Align ErtsThrPrgrLaterOp when free'ing tracerLukas Larsson
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.

We want to know the total size of literals of all heap fragmens.
2016-08-01erts: Remove the need for copying of literalsBjörn-Egil Dahlberg
* Literals are not copied between processes for messages or spawn Increases performance of message sent and processes spawned when literals are involved in messages or arguments.

2016-07-21erts: Fix internal hashing entropy for mapsBjörn-Egil Dahlberg
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.

2016-07-11erts: After a call to a tracer nif, reset htopLukas Larsson
This is needed in order for the heap to never contain any pointers to invalid memory. This is good for performance and debugging reasons.
2016-07-11erts: Fix deadlock in ets:update_counter/4Sverker Eriksson
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.
2016-07-11erts: Optimize db_finalize_dbterm_hashSverker Eriksson
Always free term after WUNLOCK_HASH
2016-07-08erts: Fix GC overrun bug in 'bsl' op with small Op1Sverker Eriksson
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.
2016-07-08erts: Check if return_to trace is enabled for bifLukas Larsson
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.
2016-07-06check_process_code: Sweep HiPE stack for literalsMagnus Lång
Because check_process_code neglected checking the HiPE stack for references to the literal area, such references would survive the purge and subsequent deletion of a module and its literal area. These dangling references would then cause incorrect behaviour or even hard crashes of the VM. By simply adding a scan of the HiPE stack to check_process_code and erts_garbage_collect_literals, this problem is fixed. In order to support full stack walks without deleting the graylimit trap, a new stack walking interface function, nstack_walk_init_sdesc_ignore_trap() was introduced.
