Add support for Imagination Technologies Meta

Add support for Imagination Technologies Meta architecture (the
architecture/ABI is usually referred to as metag in code). The Meta
Linux kernel port is in the process of being upstreamed for v3.9 so it
uses generic system call numbers.

sys_lookup_dcookie writes a filename to buffer argument, so I've set
TF flag.
nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h
so I've left it blank.
truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit
args which are packed tightly on metag, so less arguments on metag.
fchdir/llseek takes a file descriptor so s/TF/TD/
sync_file_range has 2 64bit args so uses 6 args, so s/4/6/
timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/
shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args.
oldgetrlimit is just getrlimit for metag.
add TM flag to various memory syscalls.
metag doesn't directly use sys_mmap_pgoff for mmap2.
prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag.
fanotify_init doesn't appear to take a file descriptor so remove TD.
Add kcmp syscall.
