2431e87477 8129573: CollectedHeap::fill_with_objects() needs to use multiple arrays in 32 bit mode too 
In JDK-8042668 we introduced a custom fill threshold for G1. This leads to CollectedHeap::fill_with_objects create too large objects in G1 when using it in 32 bit mode, as the code to create multiple filler objects is IFDEF'ed out on 32 bit. Enable this code on 32 bit too.
