pkg/compiler: calculate more precise sizes for arguments

If we have:

ioctl(fd fd, cmd int32)
ioctl$FOO(fd fd, cmd const[FOO])

Currently we assume that cmd size in ioctl$FOO is sizeof(void*).
However, we know that in ioctl it's specified as int32,
so we can infer that the actual syscall size is 4.

This massively reduces sizes of socket/setsockopt/getsockopt/ioctl
and some other syscalls, which is good because we now use physical
size in mutation/hints and some other places.

This will also enable not morphing ioctl's into other ioctl's.
