Clarifying the interpretation path for the "constr_with_binding" argument.
This fixes an inconsistency introduced in 554a6c806 (svn r12603) where
both interp_constr_with_bindings and interp_open_constr_with_bindings
were going through interp_open_constr (no type classes so as to not to
commit too early on irreversible choices, accepting unresolved holes).
We fix this by having interp_constr_with_bindings going to
interp_constr (using type classes and failing on unresolved evars).
The external impact is that any TACTIC EXTEND which refers to
constr_with_binding has now to decide whether it intends it to use
what the name suggest (using type classes and to fail if evars remain
unresolved), thus keeping constr_with_binding, or the actual behavior
which requires to use open_constr_with_bindings for strict
compatibility.
