/**
* CloogLoop structure:
* this structure contains all the informations of a loop generated or to be
* generated.
* - if the loop has not been processed yet (it is not a result of a call to
* cloog_loop_generate), the domain is the whole iteration domain of a given
* block, the stride is 1 (i.e. there is no stride), block is necessarily not
* NULL and inner is NULL.
* - if the loop comes as a result of a cloog_loop_generate call, the domain
* describes the constraints (guards and loop bounds) for only one dimension
* (the last one: outer dimensions being considered as parameters), the stride
* may differ from one (this means that on the considered dimension, a step of
* 'stride' must be considered between integral point, the first integral
* point to be considered being the lower bound of the loop), inner may differ
* from NULL, meaning that there are further dimensions and nesting levels in
* the loop.
