isl_space_set_dim_id: also set id of parameter in nested spaces
isl_space_set_dim_id: also set id of parameter in nested spaces

A nested space is supposed to have the same parameters as
the nesting space, so if the id of a parameter in the nesting
space space changes, it has to be changed in the nested spaces too.
