More compilation fixes.

Should we add a proxy_port that does the v->p address translation?
Should the proxy port return a fault on translation errors, if we add one?

arch/alpha/alpha_linux_process.cc:
    Syscalls use a memPort through the CPU now instead of a xc functional memory.
cpu/base.hh:
    Add a pointer to the memPort syscalls will use.  Should this be a proxy_port that does address translation?
cpu/exec_context.cc:
cpu/exec_context.hh:
    Remove functional memory from the exec context
cpu/simple/cpu.cc:
    Set the memPort to be used as the syscall port as the dcache port
sim/syscall_emul.cc:
sim/syscall_emul.hh:
    Syscalls use a memPort through the CPU now instead of a xc functional memory.
    Also, fix the fact that readStringFunctional doesn't return a fault... should proxy_port handle this because it is doing the translation?
