v1->v2:
with optimization suggested by Jakub patch 4 safety check became cheap enough.

Several improvements to verifier state logic.
Patch 1 - trivial optimization
Patch 3 - significant optimization for stack state equivalence
Patch 4 - safety check for liveness and prep for future state merging

Alexei Starovoitov (4):
  bpf: speed up stacksafe check
  selftests/bpf: check insn processed in test_verifier
  bpf: improve stacksafe state comparison
  bpf: add self-check logic to liveness analysis
