prog: profile what consumes space in exec encoding

Allow to profile how many bytes are consumed for what in the exec encoding.
The profile shows there are not many opportunities left.
53% are consumed by data blobs.
13% for const args.
18% for non-arg things (syscall number, copyout index, props, etc).
