Combine masks with a macro to be compatible with AVX-512.



See merge request !417

Conflicts:
	src/runner_doiact_vec.c

Fix for AVX-512 compilation. Use the vec_mask_and macro and not vec_and when dealing with masks.

I had to do this to be able to compile on the AVX512 system. Does this correction make sense to you ?

Pad properties with sensible values to prevent floating point exceptions.

Try again. I have ran the test that fails in the Jenkins script 3 or 4 times and it runs fine.

Bug inside debug checks.

There was an extra `{` on line 637 of `runner_doiact_vec.c` that I missed because I never compiled debugging checks enabled. I also formatted the rest of the code, which messes up the diff in gitlab.

Doself2 vectorisation

Implements:
* `runner_doself2_force_vec` a vectorised version of the `DOSELF2` for force interactions.
* Updates particle cache with properties needed for force interactions.
* Vectorised interaction functions for the force using 1 and 2 vectors, which are tested in `testInteractions.c`

Changed call to part_is_active to new function. Also removed unnecessary load of v_hj in runner_doself2_vec.

Created a new function to check that a particle is active, without passing in a pointer to the engine.

Use getticks() to get enough randomness when enqueing tasks without owners.

How about this version ?

Added cpuid for Kaby Lake processor and corresponding compilation flags.

Could you let me know whether this works ? I think I got the correct cpuid pattern for KabyLake...

Make the expected number of tasks per cell a parameter.

Previously we had a max of 96, much smaller numbers will work depending on the job
