Module Glob_term

Untyped intermediate terms

glob_constr comes after constr_expr and before constr.

Resolution of names, insertion of implicit arguments placeholder, and notations are done, but coercions, inference of implicit arguments and pattern-matching compilation are not.

Hack for funind, DO NOT USE

Note that producing the similar Constrexpr.CRawType for printing is OK, just don't try to reinterp it.
