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.

This patch implemented the setxuid and setxgid syscalls for Alpha.
These syscalls return two values, both uid/euid and gid/egid.
In addition to returning the first value in $v0, the additional
value is returned in the $a4 register.
The syscalls are used instead of the separate syscalls for those values
used on other architectures (this is probably because Alpha Linux started
out syscall compatible with DEC/OSF/Tru64).
With this patch, the perlbmk benchmarks from Spec2000 run properly.

On Alpha the target to native fcntl definitions were missing. Because of
