LGTM! Thank you, Abid!

One minor comment: can you please add a line of description for `fircg_XDeclareOp` saying that most of the operands are inherited from `fir_DeclareOp` except for the shape and shift operands that are "expanded" forms of the corresponding shape/shift operands of `fir_DeclareOp`?
