      [AsmWriter] Do not write a comma when varargs is the only argument
      
      Fixes https://github.com/llvm/llvm-project/issues/56544
      
      AsmWriter always writes ", ..." when a tail call has a varargs argument. This patch only writes the ", " when there is an argument before the varargs argument.
      
      I did not write a dedicated test this for this change, but I modified an existing test that will test for a regression.
