selftests/bpf: Test variable offset stack access
commit 8ff80e96e3ccea5ff0a890d4f18997e0344dbec2 upstream.
Test different scenarios of indirect variable-offset stack access: out of
bound access (>0), min_off below initialized part of the stack,
max_off+size above initialized part of the stack, initialized stack.
Example of output:
...
#856/p indirect variable-offset stack access, out of bound OK
#857/p indirect variable-offset stack access, max_off+size > max_initialized OK
#858/p indirect variable-offset stack access, min_off < min_initialized OK
#859/p indirect variable-offset stack access, ok OK
...
