Helge Deller 5915b67013 target/hppa: Avoid accessing %gr0 when raising exception
The value of unwind_breg may reference register %r0, but we need to avoid
accessing gr0 directly and use the value 0 instead.

At runtime I've seen unwind_breg being zero with the Linux kernel when
rfi is used to jump to smp_callin().
