3bbb997d - [flang] Disambiguate descriptor and data addresses in FIR AA. (#179774)

[flang] Disambiguate descriptor and data addresses in FIR AA. (#179774) This change basically treats the descriptors' and data loads as non-aliasing (with one exception) same way as we do it for the purpose of the TBAA tags generation for LLVM to do better optimizations. This change enables more LICM in Flang MLIR.
