8266740: Shenandoah: Heap region count calculation still wrong after JDK-8265239 #3922

@zhengyu123 zhengyu123 commented May 7, 2021

JDK-8265239 only addressed heap size that needed to be aligned to region size, it did not address the adjustment needed when use large page.

To avoid all the complication, I purpose to defer region count calculation until heap size adjustment is done.
