Exit with negative numbers causes assertion failure #9659
Description
I probably shoudln't be doing this, but when I use the exit builtin with a negative number, I get an assertion failure. For example, running fish -c 'exit -1' gives:
warning: builtin exit returned invalid exit code -1
error: /home/abuild/rpmbuild/BUILD/fish-3.6.0/src/proc.h:97: failed assertion: ret >= 0 && "trying to create proc_status_t from failed wait{,id,pid}() call" " or invalid builtin exit code!"
error: Backtrace:

fish: Job 1, 'fish -c 'exit -1'' terminated by signal SIGABRT (Abort)
Note that the crash is in the fish that I just spawned to run exit -1, not the shell used to spawn fish.
