In above backtrace TargetLibraryInfoWrapperPass instance is created implicitly because PreISelIntrinsicLoweringPass depends on TargetLibraryInfoWrapperPass: https://github.com/llvm/llvm-project/blob/17e6f51e51d36c0f784f6c400680e4aebac12d13/llvm/lib/CodeGen/PreISelIntrinsicLowering.cpp#L805C28-L805C56
Since TargetLibraryInfoWrapperPass is not created beforehand, so it is created right before adding PreISelIntrinsicLoweringPass.
I think it should be good to add both TargetLibraryInfoWrapperPass and RuntimeLibraryInfoWrapper to PM explicitly.
