/* Information about a band within a schedule.
*
* n is the number of scheduling dimensions within the band.
* coincident is an array of length n, indicating whether a scheduling dimension
* satisfies the coincidence constraints in the sense that
* the corresponding dependence distances are zero.
* permutable is set if the band is permutable.
* mupa is the partial schedule corresponding to this band. The dimension
* of mupa is equal to n.
* loop_type contains the loop AST generation types for the members
* in the band. It may be NULL, if all members are
* of type isl_ast_loop_default.
* isolate_loop_type contains the loop AST generation types for the members
* in the band for the isolated part. It may be NULL, if all members are
* of type isl_ast_loop_default.
* ast_build_options are the remaining AST build options associated
* to the band.
* anchored is set if the node depends on its position in the schedule tree.
* In particular, it is set if the AST build options include
* an isolate option.
