2016-09-05Implement the new ceil/1 and floor/1 guard BIFsBjörn Gustavsson
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of Erlang language). They are guard BIFs because trunc/1 is a guard BIF. It would be strange to have trunc/1 as a part of the language, but not ceil/1 and floor/1.

2016-09-01compiler: Eliminate use of sys_pre_expandBjörn Gustavsson
sys_pre_expand previously did a lot more work, for example, translating records and funs, but now is merely a grab bag of small transformations. Move those transformations to v3_core.

2016-08-31Avoid selective receive in code-purger processRickard Green
The code purger process handles vast amounts of messages when there are lots of processes alive. A single message in the message queue that does not match will in such cases cause lots of extra work. The code purger process now always picks the first message in the message queue, and by this avoid this extra work.

2016-08-29Fix purge of codeRickard Green
Ensure that we cannot get any dangling pointers into code that has been purged. This is done by a two phase purge. At first phase all fun entries pointing into the code to purge are marked for purge. All processes trying to call these funs will be suspended and by this we avoid getting new direct references into the code. When all processes has been checked, these processes are resumed. The new purge strategy now also completely ignore the existence of indirect references to the code (funs). If such exist, they will cause bad fun exceptions to the caller, but will not prevent a soft purge or cause a kill of a process having such live references during a hard purge. This since it is impossible to give any guarantees that no processes in the system have such indirect references. Even when the system is completely clean from such references, new ones can appear via distribution and/or disk.
