Since clang 16 is the version for Ubuntu 23 04/Fedora 38 and is easy enough to fix..

fix getOperand out of range 
This commit fixes a sloppy function call that should normally check the number of insn's Operand before calling insn's getOperand method. The fix is that if it is 0 it should continue the loop.
I solved problem https://github.com/AFLplusplus/AFLplusplus/issues/1688#issue-1648543691 using this modification

afd2ea90df LLVM plugin 16+ support proposal. 
- Lifting the standard to C++17.
- Beyond the cosmetic changes, it boils down to BasicBlock::getInstList being
  no longer available (and reading the header it is no accident).

f84ea69660 Fix child reaping on fuzzer termination 
This commit contains the following changes:
    - Call `waitpid()` on the child and the fork server when terminating the
      fuzzer; thus, we do not end up with zombies.
    - Rename `fsrv.kill_signal` to `fsrv.child_kill_signal`, since the
      documentation states that the signal is used to terminate the *child*.
    - Use SIGTERM instead of fsrv.(child)_kill_signal, thus the fork server
      can always reap the child.

5452d4652b Fix naming clash between AFL's sancov LTO pass and upstream sancov pass 
There was some confusion here due to name reuse. The
initializeModuleSanitizerCoverageLegacyPassPass() function was
actually calling the initialization of the upstream pass (which
no longer supports legacy PM and thus fails to build on LLVM 15).
The intention was to call the LTO initialization here.

Fix this by renaming symbols to avoid collision.

36c46b9579 Fix LLVM 15 build 
By removing ModuleSanitizerCoverageLegacyPass, which is completely
unused.

There was some confusing between the initialization function for
the upstream sancov pass and AFLs own implementation.
