| Fix up the VCPU state when a syscall is interrupted by a signal. |

| To do this, we determine the precise state of the syscall by |
| looking at the (real) rip at the time the signal happened. The |
| syscall sequence looks like: |
| |
| 1. unblock signals |
| 2. perform syscall |

| [2] restart syscall hasn't started, or kernel wants to restart |
| [2-3) save syscall complete, but results not saved |
| [3-4) syscall complete, results saved |
| |
| Sometimes we never want to restart an interrupted syscall (because |
| sigaction says not to), so we only restart if "restart" is True. |
| |
| This will also call VG_(post_syscall)() if the syscall has actually |
| completed (either because it was interrupted, or because it |
| actually finished). It will not call VG_(post_syscall)() if the |
| syscall is set up for restart, which means that the pre-wrapper may |
