to allow mixing of 'next' and 'prev' operations.

flatmap: Small map
hashmap: Large map
map: flatmap or hashmap

Strategy: Calculate an over estimation of heap size that will give
such a low probability for overflow, that "it will not happen".
Scary assumption 1: Uniformly distributed hash values.
Scary assumption 2: Tree size is normally distributed (right?)

by calling make_hash2.

MAP_DEF and HASHMAP_DEF must have adjacent values

The old hashing did not care which value belonged to which key,
for example:
would hash the same.

The expression,
#{} =:= M
where M was any Map, would always result in 'true'.
This commit fixes this issue by first comparing sizes for
both terms and then checking for size zero.

This port has support for both non-smp and smp.
It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.

Commit d5c238473b9cec819d93faaef4ccc00ddb60465f added a third
argument to the cmp() function, but did not change the code generation
of native code that called cmp().
Name the new functions with an "erts_" prefix, and reinstate the
old cmp() function with two arguments.
We don't have to keep a cmp() function in the halfword emulator,
since HiPE does not support the halfword emulator.

Uses total order of types meaning int < float

The hashing a map in these functions uses the same strategy
as the other terms. The exception being a prime number with size
so we do not get erlang:phash(#{}) -> 1 which would be the same
as erlang:phash({}) and erlang:phash(<<>>). Same argument for
erlang:hash/1.

big_buf was one word too short on 32-bit emulators causing
memory corruption.
Seems like this did not cause a problem before the ESTACK memory layout
was changed in 172ebf11dc455e22b87f.

|
for the temporary conversion from float to big.
Preparation for coming bugfix of 'big_buf' array size.
|
|
This is not a clean refactor. It changes the behaviour slightly
of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used
as-is and not copied into default_stack. This will hopefully fix an
illusive memory leak that valgrind is reporting.

* rickard/garbage_collect/OTP-11388:
Parallel check_process_code when code_server purge a module
Functionality for disabling garbage collection

Execution of system tasks in context of another process

A process requesting a system task to be executed in the context of
another process will be notified by a message when the task has
executed. This message will be on the form:
{RequestType, RequestId, Pid, Result}.
A process requesting a system task to be executed can set priority
on the system task. The requester typically set the same priority
on the task as its own process priority, and by this avoiding
priority inversion. A request for execution of a system task is
made by calling the statically linked in NIF
erts_internal:request_system_task(Pid, Prio, Request). This is an
undocumented ERTS internal function that should remain so. It
should *only* be called from BIF implementations.
Currently defined system tasks are:
* garbage_collect
* check_process_code
Further system tasks can and will be implemented in the future.
The erlang:garbage_collect/[1,2] and erlang:check_process_code/[2,3]
BIFs are now implemented using system tasks. Both the
'garbage_collect' and the 'check_process_code' operations perform
or may perform garbage_collections. By doing these via the
system task functionality all garbage collect operations in the
system will be performed solely in the context of the process
being garbage collected. This makes it possible to later implement
functionality for disabling garbage collection of a process over
context switches.
Newly introduced BIFs:
* erlang:garbage_collect/2 - The new second argument is an option
list. Introduced option:
* {async, RequestId} - making it possible for users to issue
asynchronous garbage collect requests.
* erlang:check_process_code/3 - The new third argument is an
option list. Introduced options:
* {async, RequestId} - making it possible for users to issue
asynchronous check process code requests.
* {allow_gc, boolean()} - making it possible to issue requests
that aren't allowed to garbage collect (operation will abort
if gc should be needed).
These options have been introduced as a preparation for
parallelization of check_process_code operations when the
code_server is about to purge a module.
