[omp, hsa] Do not gridify simd constructs
2016-02-26 Martin Jambor <mjambor@suse.cz>
* omp-low.c (grid_find_ungridifiable_statement): Store problematic
statements to wi->info. Also disallow omp simd constructs.
(grid_target_follows_gridifiable_pattern): Use wi.info to dump reason
for not gridifying. Dump special string for omp_for.
