updating sessions that have been updated

This makes sessions slightly more stable across load/save cycles.

Exported [close_record_invariant] function from pdecl.ml so
that it can also be used in pmodule.ml

Rejecting when the refinement type does not present an invariant
and the refined type does.

Refinement code requires private types to reside in
separate program declarations. So we split type decls
into chunks where all non-free types are declared
separately and only constructible (Ddata) types are
kept together. The code preserves the original order
wherever possible.

Also, export ls_of_rs and fd_of_rs from Expr: these are
used everywhere in src/mlw anyway.

Also, remove some range/float-related "assert false".

Generation of type invariants VC (wip).

Somes experiments around the generation of type invariants implication.

metas are stored in a new field pd_metas aside the field pd_pure
