Commit llvm/llvm-project@46f3ade introduced a notion of printing the attributes on the left to improve the printing of attributes attached to variable declarations. The intent was to produce more GCC compatible code because clang tends to print the attributes on the right hand side which is not accepted by gcc. This approach has increased the complexity in tablegen and the attrubutes themselves as now the are supposed to know where they could appear. That lead to mishandling of the `override` keyword which is modelled as an attribute in clang. This patch takes an inspiration from the existing approach and tries to keep the position of the attributes as they were written. To do so we use simpler heuristic which checks if the source locations of the attribute precedes the declaration. If so, it is considered to be printed before the declaration.
