RFR: 8328934: Assert that ABS input and output are legal [v5]

[Aleksey Shipilev]

> This should protect us from future accidents around `abs` misuse. We have fixed a few separately. I plan to use this as the litmus test in update releases to detect missing backports for actual fixes. I am running more tests to see if we have any other sightings in current codebase, but this can be reviewed for sanity meanwhile.

>  - [ ] Linux x86_64 server fastdebug, 100K Fuzzer tests
