[lilliput-jdk17u:lilliput] RFR: 8310573: [Lilliput/JDK17] Revert assert removals for -UCOH paths

[Aleksey Shipilev]

We have plenty of removed asserts that were unsafe when +UCOH was enabled. But those asserts should persist and be active on -UCOH paths. This change reverts most of the assert removals.

Additional testing:
 - [ ] Linux x86_64 fastdebug `tier1` (default, `-UCOH`)
 - [ ] Linux x86_64 fastdebug `tier1` (`+UCOH`)
