many functions in racket/function don't work

[stchang]

curry and functions that use it (disjoin, etc) fail with error:

kw.rkt.js:1 Uncaught TypeError: M0.__rjs_quoted__.procedure_reduce_arity_mask is not a function

I think that procedure-reduce-arity-mask could just be the identity function for many purposes.
