RFR: 8333098: ubsan: bytecodeInfo.cpp:318:59: runtime error: division by zero

[Matthias Baesken]

When running test
compiler/classUnloading/methodUnloading/TestOverloadCompileQueues.java
with ubsan enabled binaries we run into the issue reported below.
Reason seems to be that we divide by zero in the code in some special cases (we should instead check for `CompilationPolicy::min_invocations() == 0 `and handle it separately).
