Modify the emulated system calls to support running the SPEC Int

benchmarks for alpha-linux.

arch/alpha/alpha_linux_process.cc:
    Added some more ioctl commands to ignore.
    Set unlink and rename to the new functions.
    Ignore setrlimit, times and rt_sigaction.
    Should eventually provide a function for times.
arch/alpha/alpha_tru64_process.cc:
    Added some more ioctl commands to ignore.
    Set unlink and rename to the new functions.
    Ignore setrlimit.
sim/syscall_emul.cc:
    Added implementations for unlink and rename.
sim/syscall_emul.hh:
    Added unlink and rename functions.
    Added a couple more ioctl requests to ignore.
    Print out the PC of any ioctl commands that fail.
