I tried to mirror the cases handled by `Decl::getFunctionType()` from
`clang/lib/AST/DeclBase.cpp`. My thinking if there is some `Decl` that is not
handled by `Decl::getFunctionType()`, then it should not be expected that it is
handled by `getFunctionOrMethodParam()`, which tends to be below
`Decl::getFunctionType()` in the chain. For alloc_align attribute,
`Decl::getFunctionType()` is called on the Decl first (through
`getFunctionOrMethodResultType`) and if that returns nullptr then the call to
`getFunctionOrMethodParam()` is not not even reached.
