Make typecheck and typecheck-args the same order of arguments

[jcubic]

typecheck-args is used only in few places, but both functions should have the same API.

Here is example usage:

(typecheck "some" fn "function")
(typecheck-args (vector "pair" "nil") "some" lists)

typecheck-args is used with curry:

(define numbers? (curry typecheck-args "number"))

That's why the first argument is type, so you can provide label and argument when calling numbers?

typecheck should be modified to have the same API.
