Making detyping potentially lazy.
The internal detype function takes an additional arguments dictating
whether it should be eager or lazy.
We introduce a new type of delayed `DAst.t` AST nodes and use it for
`glob_constr`.
Such type, instead of only containing a value, it can contain a lazy
computation too. We use a GADT to discriminate between both uses
statically, so that no delayed terms ever happen to be
marshalled (which would raise anomalies).
We also fix a regression in the test-suite:
Mixing laziness and effects is a well-known hell. Here, an exception
that was raised for mere control purpose was delayed and raised at a
later time as an anomaly. We make the offending function eager.
