Module Unbox_specialised_args
When approximations of specialised arguments indicate that they are closures or blocks, add more specialised arguments corresponding to the projections from such blocks (with definitions of such projections lifted out), such that the original specialised arguments may later be eliminated.
This in particular enables elimination of closure allocations in examples such as:
let rec map f = function | -> | a::l -> let r = f a in r :: map f l
let g x = map (fun y -> x + y) 1; 2; 3; 4
Here, the specialised version of map initially has a specialised argument f; and upon inlining there will be a projection of x from the closure of f. This pass adds a new specialised argument to carry that projection, at which point the closure of f is redundant.
