In eclipse-openj9#19388, we are fixing up stack references of unmounted continuation for scavenge backout during reverseForwardedObject(), but the fixup would depend on the related resverseForwardedPointer installed, so the scan for fix-up need to be done after all resverseForwardedPointer are installed, otherwise some fix-up would miss. Using backoutContinuationObjects() to scan/fixup all of continuation stack references in evacuate region. Signed-off-by: hulin <[email protected]>
