branch and alub overlap in their use cases, but the backends rely on
knowing that the result is unused in their lowering of branch. By
extending alub so that the destination is optional, it can fully replace
branch.
This simplifies rtl by reducing code duplication and the number of
instructions.
Also, in the x86 and arm backends, we can now use 'test' and
{'tst','mvn','teq'} to lower some alubs without destinations. This is
particularly good for x86, as sequences such as 'is_boxed' type tests
now get shorter (both from not needing a mov to copy the variable, but
also from the fact that 'testb' encodes shorter than 'andq').

Jump functions returns the state after performing jump calculation to a
rand module internal state, which is equivalent to perform a large
number of calls of calculating new states for XorShift*/+ algorithms.
This commit add jump functions for exsplus and exs1024 algorithms, and a
wrapper function jump/1. The wrapper function will cause error with
reason "not_implemented" if the jump function for the algorithm is not
implemented.
This commit adds following new functionalities:
- Add new functions rand:jump/0 and rand:jump/1
- Add the member jump to type alg_handler(), a fun for performing
the jump function
- Add jump functions for exsplus, equivalent to 2^64 calls
- Add jump functions for exs1024, equivalent to 2^512 calls
- Revise seed_put/1, seed/1, seed/2
See <https://github.com/erlang/otp/pull/1235#discussion_r86950557>
- Add dummy jump function for exs64 calling
erlang:error(not_implemented)
- Add jump function test cases as follows:
* Add Common Test group reference_jump
* Add tests for jump/0 to reference_jump_procdict/1
* Rename tests for jump/1 to reference_jump_state/1
* Rename gen_jump/1 to gen_jump_1/1
* Add Common Tests reference_jump_procdict and reference_jump_state
to the group reference_jump
- Add jump function documentation
This commit also changes the Copyright year for Kenji Rikitake's code
from 2015 to 2015-2016.

Continuations returned from mnesia_ext backends were originally wrapped with
the backend module, but that was a remnant of the earliest implementation,
and is not actually needed, since Mnesia already knows what the table
storage type is when it applies the continuation. When mnesia_ext was ported
to OTP 19, the wrapper got changed to use the table type alias instead of
the module, which triggered an error in the mnesia_eleveldb backend. This
patch removes the wrapping completely.

ECC certs should preferably use SHA2, this is what we want to be

Update to look for -lodbc as well as default to /usr/local as you will need to brew install libiodbc.

The default value of 'mod' is '[]' and 'start_phases' is 'undefined'
in .app, but this value was not accepted if given in
the .app file. This is now corrected.

The constant ?WORD_WIDTH is renamed ?BITS_IN_WORD, and a new constant
?BITS_IN_BYTE is introduced.
Additionally, a bug in a currently unused case clause of
llvm_type_from_size/1 is fixed (the size of a word was hardcoded to 64
bits).

Optimize sets:add_element/2 when adding an element that is already present, and
sets:del_element/2 when the element to be deleted is not present. This optimization
can make certain operations, such as sets:union/2 with many overlapping elements,
up to two orders of magnitude faster.
