(** Pop the current frame.
Drop all the local variables (which has the effect of moving their values to
dummy variables, after ending the proper borrows of course) but the return
variable, move the return value out of the return variable, remove all the
local variables (but preserve the abstractions!), remove the
{!constructor:Contexts.env_elem.EFrame} indicator delimiting the current frame and
handle the return value to the continuation.
If the boolean is false, we don't move the return value, and call the
continuation with [None].

(** Helper.
Create a list of abstractions from a list of regions groups, and insert
them in the context.
Parameters:
- [call_id]
- [kind]
- [rgl]: "region group list"
- [region_can_end]: gives the region groups from which we generate functions
which can end or not.
- [compute_abs_avalues]: this function must compute, given an initialized,
empty (i.e., with no avalues) abstraction, compute the avalues which
should be inserted in this abstraction before we insert it in the context.
Note that this function may update the context: it is necessary when
computing borrow projections, for instance.
