The phrasing "no process can access the ETS table in the middle of the operation" implies that the entire table is looked during the operation, which is not true if `write_concurrency` is enabled.

2019-02-21erts: Move reason in dist messages to payloadLukas Larsson
The dist messages EXIT, EXIT2 and MONITOR_DOWN have been updated with new versions that send the reason term as part of the payload of the message instead of as part of the control message. This allows the decode of the reason to be done by the receiving process instead of the dist entry which in turn makes it possible for multiple decodes to be done in parallel. This change is done in order to make it easier to fragment the potentially large payload of EXIT, EXIT2 and MONITOR_DOWN into multiple distribution messages. OTP-15611
2019-02-21erts: Remove a copy of distribution data payloadLukas Larsson
Before this change the inet driver was in list mode and thus the data from it had to be copied when received by the dist entry. This change puts the tcp port in binary mode and makes the any refc binary created by it be used all the way to the process where it is decoded. Thus eliminating one copy of the entire message payload.

2019-02-21beam_ssa_type: Use types from some 'lists' functionsBjörn Gustavsson
This commit lets the compiler know about the return type of some of the functions in the `lists` module. Knowing about the return will allow the compiler to emit fewer type test instructions, and also fewer instructions for throwing `case_clause` or `badmatch` exceptions, thus producing slightly faster and more compact code. This change makes the `lists` module a part of the language, but it could be argued that it already is because several functions (e.g. `member/2` and `keymember/3`) are implemented in as BIFs in the runtime system. Therefore, a user cannot simply change the `lists` module and expect everything to continue working as before. The compiler will now know the return types for the following functions: all/2 any/2 keymember/3 member/2 prefix/2 suffix/2 dropwhile/2 duplicate/2 filter/2 flatten/1 map/2 mapfoldl/3 mapfoldr/3 partition/2 reverse/1 sort/1 splitwith/1 takewhile/1 unzip/1 usort/1 zip/2 zipwith/3
2019-02-21sys_core_fold: Remove an unsafe optimizationBjörn Gustavsson
`sys_core_fold` has an optimization of repeated pattern matching. For example, when a record is matched the first time, the pattern is remembered. When the same record is matched again, the matching does not need to be repeated, but the variables bound in the first matching can be re-used. It turns out that that there is a name capture problem when the old inliner is used. The old inliner is used when explicitly inling certain functions, and by the compiler test suites for testing the compiler. The name capture problem could be eliminated by more aggressive variable renaming when inlining. But, fortunately, given the new SSA passes, this optimization is no longer as essential as it used to be. Removing the optimization turns out to be mostly benefical, leading to a smaller stack frame in many cases. Also remove the optimizations of `element/2`, `is_record/3`, and `setelement/3` from `sys_core_fold`. Because matched patterns are no longer remembered, those optimizations can very rarely be applied any more. (Those same optimizations are already done in `beam_ssa_type`.)

2019-02-21beam_ssa_opt: Do local CSE of get_tuple_element instructionsBjörn Gustavsson
For some reason, a `get_tuple_element` instruction was not deemed suitble for local common sub expression elimination. It turns out that enabling CSE for `get_tuple_element` is benefical. It will also be even more benefical in a future commit where some of the optimizations in `sys_core_fold` are removed.
