Yonghong Song 0a0fdc64b6 bpf: Add precision marking and backtracking for stack argument slots ...

Extend the precision marking and backtracking infrastructure to
support stack argument slots (r11-based accesses). Without this,
precision demands for scalar values passed through stack arguments
are silently dropped, which could allow the verifier to incorrectly
prune states with different constant values in stack arg slots.
