YJIT: Handle special case of splat and rest lining up (#7422)
If you have a method that takes rest arguments and a splat call that
happens to line up perfectly with that rest, you can just dupe the
array rather than move anything around. We still have to dupe, because
people could have a custom to_a method or something like that which
means it is hard to guarantee we have exclusive access to that array.
Example:
```ruby
def foo(a, b, *rest)
end
foo(1, 2, *[3, 4])
```
