Neither can be used for type subtraction, so the default BIF
handler suits them just fine.

While this is strictly only relevant for bs_get_binary2, we should
never build anything while matching a message, so it ought to be
safe to remove this last raw use of propagate_fragility.

Granted, it's replaced with a thin wrapper, but it'll simplify
migration to the new type format.

The expansion of record field updates, when more than one field is
updated, but not a majority of the fields, will create a sequence of
calls to `erlang:setelement(Index, Value, Tuple)` where Tuple in the
first call is the original record tuple, and in the subsequent calls
Tuple is the result of the previous call. Furthermore, all Index
values are constant positive integers, and the first call to
`setelement` will have the greatest index. Thus all the following
calls do not actually need to test at run-time whether Tuple has type
tuple, nor that the index is within the tuple bounds.
Since OTP R7, the `sys_core_dsetel` pass, run as the very last Core
Erlang pass, has optimized this sequence of `setelement` calls to use
a special destructive version of `setelement` (called
`set_tuple_element`) for all but the very first `setelement` in the
sequence.
It turns out that the presence of the `set_tuple_element` in SSA code
is awkward and can prevent or complicate type analysis and aggressive
optimizations.
Therefore, this commit removes the `sys_core_dsetel` pass and
reimplements it for SSA code. The optimization will be done in the
`beam_ssa_pre_codegen` pass (that is, just before code generation and
after running all other SSA code optimization passes).
In most cases, the resulting BEAM code is identical to previous
code. For a few modules, the BEAM code is actually slightly better,
with smaller stack frames.

Also make a weaker spec in ssl_internal.hrl for now as it creates

Previously this test suite used a short-cut that didn't work well with the new crypto
API being experimented with in other branches.
This commit uses the legacy decode and decryption functions in ssh_transport. It is of
course normally a bad idea to test something with itself. However, other test suites
test the interoperability with OpenSSH and by that implicitly of the decoding/decryption.
The ssh_protocol_SUITE tests sending malformed and even malicious PDUs to the Erlang/OTP
SSH implementation. Therefore the tests in this suite is not dependent on being different
than thoose of the system under test.

This fixes compiling against older OTP versions with the +r?VSN
options, which often expand to disabling certain SSA passes to
avoid new instructions.
