pet_scop_filter_skip: avoid recomputation of test expression
Commit
40ba1a0 (use an isl_multi_pw_aff to represent a skip condition,
Mon Jun 17 21:53:13 2013 +0200), changed pet_scop_filter_skip
to construct an isl_multi_pw_aff from an isl_map representation of
the skip condition. Since commit
dbee8c4 (keep track of index expressions,
Mon Jun 17 14:26:28 2013 +0200) the condition is passed
as an isl_multi_pw_aff to pet_scop_filter_skip, so there is no longer
any need for a conversion.
