8062672: JVM crashes during GC on various asserts which checks that HeapWord ptr is an oop
Summary: Crashes were caused by not disabling UseMemSetInBOT as should be done on sparc. Added support for picking up blkinit as a platform feature if available on Linux sparc. This is needed to avoid enabling UseMemSetInBOT when running on this platform.
