target-alpha: implement getxuid and getxgid syscalls
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. (Vince Weaver) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5722 c046a42c-6fe2-441c-8c8c-71466251a162
