[llvm] [Analysis][LV] Handle FMinNum/FMaxNum in RecurrenceDescriptor::getOpcode (PR #152794)

[Florian Hahn via llvm-commits]

This is very likely to be incorrect. 

There's not really a corresponding opcode and treating them the same as FMax/FMin will be incorrect. It would probably be better to update your code not to query getOpcode for those recurrence kinds.
