hg: shenandoah/jdk9/hotspot: Allow 0 as ref-proc and class-unloading frequency (turning them off). Lower defaults for frequency to every 5th cycle.

[Всеволод Толстопятов]

Hi again,

+    if (ShenandoahUnloadClassesFrequency) return false;


Shouldn't it be if (ShenandoahUnloadClassesFrequency  == 0)? :)

Also, why it's even possible to totally disable ref-processing (guess this
question is applicable to unloading either)? Shouldn't it be something
like range(1, 100)? Maybe it's worth to merge this two options?
