Replace heave array_put() with a dumb array index assignment ARRAY_PUT
and instead introduce ensure_array_size() to be called when
we know the array might need to grow.
This change also ensures the entire HASH_RANGE is always
allocated. No need for ARRAY_GET to check index any more.

by limiting table sizes to powers of 2.
This will change the default size from 10 to 8.

The message_queue_data option can have the values
- off_heap
- on_heap
- mixed
|
|

Processes remember heap fragments that are known to be fully
live due to creation in a just called BIF that yields in the
live_hf_end field. This field must not be used if we have not
disabled GC in a BIF. F_DELAY_GC has been introduced in order
to distinguish between to two different scenarios.
- F_DISABLE_GC should *only* be used by BIFs. This when
the BIF needs to yield while preventig a GC.
- F_DELAY_GC should only be used when GC is temporarily
disabled while the process is scheduled. A process must
not be scheduled out while F_DELAY_GC is set.

Make sure a heap fragment is not deallocated before all off_heap
terms have been cleared.
The fix assumes/asserts that the off_heap-lists of all additional
heap fragments are empty.
I think this bug has been harmless as hashmap nodes, which is only
ones (?) that can cause a factory to produce more heap,
are not linked in off_heap-list.

Also, some of the branches were testing sizes in bits against a constant
?MAX_BINSIZE, which was in bytes. The signed comparisons masked this
mistake. These branches have been removed since all sizes in bits that
fit in a machine word are valid binary sizes.
Finally, a test that reproduces the issue was added to bs_construct,
along with a test for one of the cases (bs_init<0>(...)) when the test
against ?MAX_BINSIZE must be changed to unsigned rather than removed.
|
|
The test whether the result would fit in a smallnum could overflow into
a negative number that would fit a smallnum. A test that reproduces the
issue was added to bs_construct_SUITE.

1. Use load factor as indicator, not used buckets.
Used buckets is a bad indicator as it makes the situation even
worse with a bad hash function.
Set grow_threshold to load factor of 160% as it roughly corresponds
to the old 80% used bucket limit.
2. Never shrink table below initial size.

huge_binary/1 did not consider that the Shift variable is not a
constant, and misses the case of a literal size.
|
|
This feature was previously missing and expressions such as
<<<<1:1>>/binary>> would succeed construction when compiled with HiPE.
A primop is_divisible is introduced to handle the case when the unit
size is not a power of two.

after major GC.
Can only be caused by distributed messages containing large maps.
Bad map hashing will increase the risk.
