  -----------
  java/openjdk: handle SIGBUS implicit null checks

Treat SIGBUS on MidnightBSD like Darwin in the BSD x86 signal handlers so C2 compressed-oops implicit null checks can reach the HotSpot null-exception continuation instead of the unsafe/MappedByteBuffer path.

Apply the MidnightBSD SIGBUS signal-handler fix to the remaining native OpenJDK ports that have the same BSD x86 compressed-oops implicit null-check path.
