wire up initialization of argument variables with BBArguments that correspond
to function arguments.  For example, we now lower:

func curried_arguments(x : Int) (y : Int) -> Int {
  return x+y
}

to:

func_decl curried_arguments
bb0(%0 : Int, %1 : Int):
  %2 = tuple (%0)
  %3 = alloc_var x, type=[byref(heap)] Int
  %4 = store %0 -> %3 [initialization]
  %5 = tuple (%1)
  %6 = alloc_var y, type=[byref(heap)] Int
  %7 = store %1 -> %6 [initialization]
  %8 = constantref +, type=(lhs : Int64, rhs : Int64) -> Int64
  %9 = load %3
  %10 = load %6
  %11 = apply %8(%9, %10)
  %12 = return (%11)
