Added `if (Call->hasOperandBundles()) return nullptr;` guard to the llvm.fcmp case. In principle FCMP_TRUE and FCMP_FALSE don't inspect operands, but to be conservative we bail out when operand bundles are present since they could enable FP exception tracking that might change the observable behavior.
