2019-03-22beam_emu.c: Avoid triggering an assertion for the wrong reasonBjörn Gustavsson
Before 2d2e78ad6e66 that introduced tail-recursive calls of BIFs, the stack was guaranteed not to be empty when `erlang:raise/3` was called from the `catch` block of a `try` (because the `try` had set up a stack frame that would be deallocated after the `raise` call). Now the stack can be empty, so the ASSERT() call in next_catch() that checks that there is a continuation pointer at the top of the stack may fail. Move the ASSERT() call to after check for empty stack. While at it, also add a comment of the reason for the assertion.

2019-03-22erts: Fix incorrect UNC path length calculationJohn Högberg
This didn't cause any issues for the most part since the path was still properly formed, but it broke down when appending the wildcards in file:list_dir/1. The ASSERT_PATH_FORMAT macro would have caught this in no time, but it went unnoticed because we don't run debug builds on Windows.

* max-au/erts/dirty_scheduler_shutdown/PR-2172/OTP-15690: erts: release dirty runqueue lock before entering endless loop when BEAM is shutting down
2019-03-21erts: release dirty runqueue lock before entering endless loop when BEAM is ↵Maxim Fedorov
shutting down This patch fixes a problem happening when BEAM is shutting down. It is possible for a dirty scheduler to take the lock, and keep it, when the system is shutting down. It may also happen that a normal scheduler decides to schedule some dirty job (example is major garbage collection that results in migrating the process into dirty CPU queue), and hangs trying to take the lock that will never be released. To fix the problem, either release the lock before entering endless wait loop, or reverse the order in which schedulers are stopped. Either fix works, and, of course, it works even better to apply both.
2019-03-20Fix reception of resume signal on process executing dirtyRickard Green
If a suspend/resume signal pair was sent to a process while it was executing dirty the resume counter on the process got into an inconsistent state. This in turn could cause the process to enter a suspended state indefinitely.
2019-03-20Optimize moving of several Y registers to X registersBjörn Gustavsson
Introduce move_src_window[234] instructions for moving several consecutively numbered Y registers to discontiguously numbered X registers. This optimization is effective because the compiler has sorted the `move` instructions in Y register order.
2019-03-20[socket|test] Improve test case preconditionMicael Karlberg
Added a fun for precondition check run before each test case is actually run. The primary reason for this is the api_to_connect test case, which does not work for a number of platforms. Also, moved the IPv6 check into this fun (instead of an explicit skip in the test case fun) for the IPv6 test cases.

With the new compiler, it has become less common with a move to x(0) before a jump. Change the move_jump instruction to take a destination as well as a source.
