update magic numbers

Numbers and .mlbuild and .mlp were not always synchronized; I only
changed the typedtree-related numbers, but used the max of both +1 on
both sides -- the .cm{o,a,x}... numbers are still non-synchronized.

Sys: Use constant for some runtime limitations.

It allows to have non-standard limits for non-standard runtime.
ie: js_of_ocaml use 32bits integer, and can handle
string much bigger than 16Mo.

New primitive: caml_alloc_dummy_function ... caml_alloc_dummy_function takes the function arity as a second argument. This new information can be used by js_of_ocaml to perform better optimization.
