x86 hvm: Improve paging performance for 64b solaris guests

The following patch provides a 'fast-path' for sh_remove_write_access()
for 64 bit Solaris HVM guests. This provides a significant performance
boost for such guests; our testing shows a 200-400% improvement in
microbenchmarks such as fork(), exit(), etc...
