If the main lock is not taken then any process running on a dirty scheduler may cause all kinds of problems.

This makes them roughly as fast as integer_to_list/1 and integer_to_binary/1.

2019-01-07erts: Fix process_SUITE:max_heap testsLukas Larsson
Make sure to flush all queued emulator logger messages before starting the test. The trap_exit_badarg could sometimes leave messages and since the handler and messages now are handled in different processes this becomes a problem.

Make length/1 yielding
2018-12-18Make length/1 yieldingBjörn Gustavsson
The guard BIF `length/1` would calculate the length of the list in one go without yielding, even if the list was were long. To make it even worse, the call to `length/1` would only cost a single reduction. This commit reimplements `length/1` so that it eats a number of reductions proportional to the length of the list, and yields if the available reductions run out.

Similar bug as for bxor fixed by abc4fd372d476821448dfb9 Ex: 1> io:format("~.16B\n", [-16#1110000000000000000 band (-1)]). -1120000000000000000 Wrong result for (-X bsl WS) band -Y. where X is any positive integer WS is erlang:system_info(wordsize)*8*N where N is 1 or larger Y is any positive integer smaller than (1 bsl WS) Fix: The subtraction of 1 (for 2-complement conversion) must be carried along all the way to the last words.
2018-12-17Use microops for BIFsMichał Muskała
This allows bif1/2/3 to share the main part of the code. The price is that we always need to copy all three temporary registers when error handling in bodies, but that should be infrequent. Additionally it makes it a bit harder to read the disasembly since now the arguments to BIFs are in the reverse order.

2018-12-13erts: Fix possible heap corruption getting atomicsTomas Abrahamsson
Due to comparison as a signed integer, when getting an unsigned atomic in the range 2^63-1..2^64-1 (when the most significant bit was set), the heap could get corrupted when the integer was retrieved: hsz would get set to zero, but the code proceeded to build a bignum. Steps to reproduce (at least on x86_64): $ erl 1> A = atomics:new(1,[{signed,false}]). 2> atomics:put(A,1,18446744073709551615). 3> atomics:get(A,1). At the last step, the shell would print some garbage and hang.

2018-12-13erts: Fix seq_trace:reset_trace dirty gc bugLukas Larsson
When seq_trace:reset_trace could be called while a process was doing a dirty GC. This triggered a race where all signals was moved to the internal signal queue during the GC which in turn caused the a heap overrun problem. This fix makes it so that the main and msgq lock are taken before the clear. This will make sure that we are allowed to do the clear.

Dispatching a function and return never use the next instruction. It's unlikely for raw_raise to use the next instruction.
