Bug #8418: when all params are optional, named arg hash maps to the first available param

Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


irb(main):028:0> def foo(arg = 1, options = {}); {arg: arg, options: options}; end; foo(a: 1)
=> {:arg=>{:a=>1}, :options=>{}}

since positional args can't follow the named hash, perhaps the named hash should map to the last possible param?
