We currently return 4 for stackmaps and patchpoints, which is very optimistic and can in rare cases cause the branch relaxation pass to fail to relax certain branches. This patch causes getInstSizeInBytes to return a pessimistic estimate of the size as the number of bytes requested in the stackmap/patchpoint. In the future, we could provide a more accurate estimate by sharing some of the logic in AArch64::LowerSTACKMAP/PATCHPOINT.
