dd2986b43b tools/syz-trace2syz/parser: parse strace bitsets 
Strace decodes bitsets like fd_set or sa_mask into the following structure: [a b c d e].
Before we couldn't parse these structures, but now parse them into the Group IR Type

88f5934633 vm: allow fine-grained control over program exit conditions 
Currently we only support canExit flag.
However there are actually 3 separate conditions:
 - program can exit normally
 - program can timeout (e.g. fuzzer test or runtest can't)
 - program can exit with error (e.g. C test can)
Allow to specify these 3 conditions separately.

603b512405 vm/gvisor: use runsc debug --stacks to diagnose 
This feature has been around longer than -trace-signal. It returns the
stacks directly, which we then append to the kernel log.

the kernel console log.
