| * | | erts: Use global trap entries for listsJohn Högberg2019-09-173-53/+10
| | | | | | | | | | | | | | | | | | | | The local ones are redundant now that the global ones can't be traced anymore.

| | | | | | | | | | | | | | | | | | | | This hides traps when BIFs are traced, making them appear as a single call + return pair.

| | |_|/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some return paths were not going through dtrace hooks so no function-return probes were being triggered on dtrace/systemtap. The return probe will now inform the user of which function it returns *from* as opposed the previous behaviour of informing where it returns *to*.

| * | | erts: Use local trap exports for list functionsJohn Högberg2019-09-164-15/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents trapping from showing up in tracing, fixing certain tests that assume the old and erroneous trace behavior for BIFs. Note that this does not fix bogus arguments showing up on exceptions as many of these functions still pass the remainder of of the list to themselves when trapping.

| * | | erts: Refactor BIF tracingJohn Högberg2019-09-1627-1078/+731
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit replaces our current BIF-specific tracing functionality with the general function/export tracing used for everything else, fixing a few longstanding issues: * BIFs that trapped to themselves, for example lists:reverse/2, would generate a call trace message for each trap but only a single return trace message. * BIFs that trapped elsewhere, like erlang:delete_module/1, would lose their return trace messages altogether. * Return/exception trace messages on tail calls would point at the function "above" the caller. * Call count tracing simply didn't work.

| * | | erts: Fix undefined behavior in $DISPATCHX()John Högberg2019-09-116-167/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some call instructions kept the export entry outside of Arg(0) for better argument packing, so the $DISPATCHX() macro faked a new instruction pointer starting at "one behind" the given argument. Some of these saved the argument on the C stack and passed that onwards to this macro, which could provoke undefined behavior if we were to jump out of the block, for example if we needed to save_calls. This commit fixes the issue by letting the macro take an argument directly, and removing the jump on save_calls. I've also taken the opportunity to move all dispatch-related macros to macros.tab as it's a pinch cleaner to gather everything there.
