lcnt:collect is documented as implicitly starting the lcnt server
but didn't do so prior to this commit. I've decided to extend this
behavior to all operations as the overhead is negligible and it's
a bit more convenient to use.

ssl: Fix alert handling so that unexpected messages are logged and alerted correctly

Strengthen beam_validator to check that the stack is initialized
when an instruction with an {f,0} operand is executed.
For example, the following code sequence:
{allocate,0,1}.
{bif,element,{f,0},[{integer,1},{x,0}],{x,0}}.
should not be accepted because the stack may be scanned if
element/2 fails. That could cause a crash or other undefined
behavior if garbage on the stack looks like a catch tag.

... in handle_common_event(), instead of passing it to
handle_own_alert() after wrapping it in a tuple with `StateName` (i.e.
`{StateName, Msg}`).
The `StateName` is passed to handle_normal_shutdown() and to
alert_user(). The latter has a clause matching it against `connection`.
Unfortunately, when the argument was in fact `{StateName, Msg}`, another
clause was executed which dropped the `active` flag value and forced it
to `false`, even if the state was actually `connection`. It meant that
later in send_or_reply(), the alert was not propagated to the user, even
though it should (`active` set to `true` or `once`).
Now that handle_common_event() always passes the actual `StateName`, the
problem is fixed.

Preferably customized cipher suites will be based on the default value.
But all may be used as base and hence it will be good to
handle anonymous suites separately as they are intended for testing purposes.

Authenticated encryption (AE) and authenticated encryption with
associated data (AEAD, variant of AE) is a form of encryption which
simultaneously provides confidentiality, integrity, and authenticity
assurances on the data.
This is more logical value then null that was used, this happened to
work as the AEAD property was derived form other data, but it is confusing!

ErLLVM: Preserve precise BEAM tailcall semantics

The BEAM compiler chooses not to perform tailcall optimisations for some
calls in tail position, for example to some built-in functions. However,
when the ErLLVM HiPE backend is used, LLVM may choose to perform
tailcall optimisation on these calls, breaking the expected semantics.
To preserve the precise semantics exhibited by BEAM, the 'notail'
marker, present in LLVM since version 3.8, is added to call instructions
that BEAM has not turned into tail calls, which inhibits LLVM from
performing tail-call optimisation in turn.

particularly slow erlc when compiler is hipe compiled.
hipe_unified_loader:load did not patch external call sites
and instead caused a double hipe mode switch per call.
hipe_unified_loader:load is only used
for early modules first loaded as beam
and by code:atomic_load and friends.
