Michael Kruse c0bc995429 [Polly] Fix prevectorization of fused loops.
The schedule of a fused loop has one isl_space per statement, such that
a conversion to a isl_map fails. However, the prevectorization is
interested in the schedule space only: Converting to the non-union
representation only after extracting the schedule range fixes the problem.

This fixes llvm.org/PR46578
