Sentinels in select_tuple_arity instructions are not proper
tuple arities and thus cannot be checked in debug.
Print them as small integers instead.

Try write directly to process heap (as before)
if the term is guaranteed not to contain any
big maps that may break the initial size estimation.

by adding a dynamic heap factory.
"binary_to_term" is now a hybrid solution with both
a call to decoded_size() to calculate needed heap space
AND possible dynamic allocation of more heap space
if needed for big maps.
The heap size returned from decoded_size() is guaranteed
to be sufficient for all term heap data except for hashmap
nodes. All hashmap nodes are created at the end of dec_term()
by invoking the heap factory interface that may allocate more
heap space on process heap or in fragments.
With this commit it is no longer guaranteed that a message
is confined to only one heap fragment.

to be better at reusing entire hashmap sub-trees.
Sub-tree reuse is detected in three cases:
1. The sub-tree top node does not exist at all in the other map.
Already implemented before this commit.
2. The exact same sub-tree exist in both maps.
Must calculate nr of keys in tree to get total size right.
3. We detect that a sub-tree only contains stuff from one of the maps.
There is still one case we don't detect. If A and B leafs have equal
keys we could also compare the values. If values are equal, further
node reuse could propagate up toward the root (by 'mix'==0).
The downside would be potentially expensive value comparisons.

Add a check to protect from segfault when erlang:get_module_info/1/2 is
called on a deleted module (i.e. with no current code). Also refactor
erts_module_info_0/1 to avoid repeated calls to erts_active_code_ix() and
remove some obsolete comments. Add test for module_info on deleted modules.

All flags was not always set when setting multiple aux work
flags at once. This scenario is fortunately quite uncommon
and only caused further delay in memory deallocations.
