If the progs are compiled into native code, isn't there optimizations that
could be done? That is, if ftrace_regs is available, and the bpf program is
just using the subset of pt_regs, is it possible that it could be compiled
to use ftrace_regs?

Forgive my ignorance on how BPF programs turn into executables when running
in the kernel.
