Add param parloops-chunk-size
2015-09-03 Tom de Vries <tom@codesourcery.com>
* doc/invoke.texi (parloops-chunk-size): Add item.
* params.def (PARAM_PARLOOPS_CHUNK_SIZE): Add DEFPARAM.
* tree-parloops.c: Include params.h.
(create_parallel_loop): Set chunk-size of schedule of omp-for loop, if
param parloops-chunk-size is used.
