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.

The +SDcpu, +SDPcpu, and +SDio options did not properly handle having their
arguments immediately following them without intervening whitespace,
e.g. +SDio20 was treated as an error. Fix all the dirty scheduler command
line options so they handle optional whitespace between them and their
associated arguments.

Exact updates on empty Maps must fail directly.

..has been successfully called.
Opened resource types (created or taken-over) were left "hanging"
leading both to memory leakage and other more strange and serious behavior.
Now a proper rollback is done.

Map source may be anything, not only registers.
|

'maps_head' was not restored when yielding. Risk for crash increases with
size and number of maps in term.

erl_drv_output_term() and erl_drv_send_term() can send messages
containing maps with the use of the new ERL_DRV_MAP.
The driver API minor version is updated as new functionality is added.

No need to use 64bit integers on 32bit machines.

and simplify code by ignoring h_limit which is always zero.

as it does the same thing as enif_get_map_value.
Replace with placeholder to be ABI backward compatible on Windows
as long as enif_find_map_value is not called.

Maps may be encoded with keys in arbitrary order. This is fine,
as long as keys are unique.

to not continue comparing keys once it has been found.

HRelease was called with wrong arguments and left garbage on heap
when key was not found.

Maps internally uses term order to store keys in an ordered fashion.

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.

* map:remove/2
* map:keys/1
* map:values/1
* map:is_key/2
* map:update/3
- Equivalent to ':=' operator in #{ K := V } maps.
* map:from_list/1
- map:from_list/1 takes any unsorted key/value list, [{K,V}], and
produces a map. Duplicate keys are removed. The latest key is kept.
* map:find/2
- Searches for a pair that *equals* input key.
* map:merge/2
- Merge two maps to one map.

To add a type-testing guard BIF, the following steps are needed:
* The BIF itself is added to bif.tab (note that it should be declared
using "ubif", not "bif"), and its implementation to erl_bif_op.c.
* erl_internal must be modified in 3 places: The type test must be
recognized as guard BIF, as a type test, and it must be auto-imported.
* There must be an instruction that implements the same type test as
the BIF (it will be used in guards). beam_utils:bif_to_test/3 must
be updated to recognize the new guard BIF.
