Remove register chain based liveness tracking:
- struct bpf_reg_state->{parent,live} fields are no longer needed;
- REG_LIVE_WRITTEN marks are superseded by bpf_mark_stack_write()
calls;
- mark_reg_read() calls are superseded by bpf_mark_stack_read();
- log.c:print_liveness() is superseded by logging in liveness.c;
- propagate_liveness() is superseded by bpf_update_live_stack();
- no need to establish register chains in is_state_visited() anymore;
- fix a bunch of tests expecting "_w" suffixes in verifier log
messages.
