This commit filters out cipher suites not to be used in TLS-1.3
We still need to add new cipher suites for TLS-1.3 and possible
add new information to the suite data structure.

Sometimes when building a tuple, there is no way to avoid an
extra `move` instruction. Consider this code:
make_tuple(A) -> {ok,A}.
The corresponding BEAM code looks like this:
{test_heap,3,1}.
{put_tuple,2,{x,1}}.
{put,{atom,ok}}.
{put,{x,0}}.
{move,{x,1},{x,0}}.
return.
To avoid overwriting the source register `{x,0}`, a `move`
instruction is necessary.
The problem doesn't exist when building a list:
%% build_list(A) -> [A].
{test_heap,2,1}.
{put_list,{x,0},nil,{x,0}}.
return.
Introduce a new `put_tuple2` instruction that builds a tuple in a
single instruction, so that the `move` instruction can be eliminated:
%% make_tuple(A) -> {ok,A}.
{test_heap,3,1}.
{put_tuple2,{x,0},{list,[{atom,ok},{x,0}]}}.
return.
Note that the BEAM loader already combines `put_tuple` and `put`
instructions into an internal instruction similar to `put_tuple2`.
Therefore the introduction of the new instruction will not speed up
execution of tuple building itself, but it will be less work for
the loader to load the new instruction.

ops.tab: Fix potentially unsafe optimization of raise/2
|
|
The operands for the raise/2 instruction are almost always in x(2) and
x(1). Therefore the loader translates the raise/2 instruction to an
i_raise/0 instruction which uses the values in x(2) and x(1). If the
operands happens to be in other registers, the loader inserts move/2
instruction to move them to x(2) and x(1).
The problem is that x(3) is used as a temporary register when
generating the move/2 instructions. That is unsafe if the
Value operand for raise/2 is x(3).
Thus:
raise x(0) x(3)
will be translated to:
move x(0) x(3)
move x(3) x(1)
move x(3) x(2)
i_raise
The Trace will be written to both x(2) and x(1).
The current compiler will never use x(3) for the Value operand,
so there is no need to patch previous releases. But a future compiler
version might allocate registers differently.

See also https://bugs.erlang.org/browse/ERL-680.
The right associative short circuit expressions 'andalso' and 'orelse'
are expanded by the Compiler (see v3_core) into 'case' expressions. If
parentheses are used to enforce left associativeness, variables are
introduced, and the time needed by Dialyzer increases exponentially.
Rather than trying to fix Dialyzer itself, v3_core now rewrites
repeated use of 'andalso' ('orelse') into right associative
expressions before creating the 'case' expressions.
