With this change we now include <asm-generic/syscalls.h> into the "tile" version of the header. To take full advantage of the prototypes there, we also change our naming convention for "struct pt_regs *" syscalls so that, e.g., _sys_execve() is the "true" syscall entry, which sets the appropriate register to point to the pt_regs before calling sys_execve(). While doing this I realized I no longer needed the fork and vfork entry point stubs, since those functions aren't in the generic syscall ABI, so I removed them as well.
