x86: Debug register emulation (Jan Kiszka)
Built on top of previously enhanced breakpoint/watchpoint support, this patch adds full debug register emulation for the x86 architecture. Many corner cases were considered, and the result was successfully tested inside a Linux guest with gdb, but I won't be surprised if one or two scenarios still behave differently in reality.
