  [llvm][CodeGen] Addressing modes for SVE stN.

This reverts commit 17b1869b72f30f2702cb1abd7222027082e49eb6.

It is an attempt to fix the failure reported at

The patch differs from the original one reviwed at
https://reviews.llvm.org/D77435 only for the use of the std::make_tuple
in building the return value of `findAddrModeSVELoadStore`:

   -  return {IsRegReg ? Opc_rr : Opc_ri, NewBase, NewOffset};
   +  return std::make_tuple(IsRegReg ? Opc_rr : Opc_ri, NewBase,

the original patch submitted at
https://github.com/llvm/llvm-project/commit/fc4e954ed5c0825cdfe3a590ff1904ef38bc47db
was failing the following build:
