Hi all,

I've been doing a mini-audit of Zero to ensure it still works with
non-standard options.  This webrev:

fixes the following issues:

  1. HotSpot would segfault with -XX:+CITime if the VM is built
     with no compilers.  The patch fixes this.
  2. The C++ interpreter doesn't support -XX:+ProfileInterpreter
     and -XX:+UseCompressedOops, and Zero doesn't support
     -XX:+TaggedStackInterpreter.  The patch disables these
     options in these configurations.

I haven't filed a bug for this, so it has no bug id yet.
