[Jikesrvm-core] 64-bit version of libvm.C

Sergiy (et al.):

o_vaddr is filled in by the OS when a SEGV is delivered. It will contain
the address that you tried to access, but for which access failed. You
definitely need it.

You also need to get the gprs in signal handlers.

My perusal of the AIX .h files suggests that mstsave is still what you
want. Not sure why what you were doing before was not quite right.
