[hsa-branch 1/9] Builtins for gridsize and currentworkgroupsize

[Martin Jambor]

Hi,

the patch below makes the griddim and currentworkgroupsize special HSA
instructions available for omp lowering through a builtin.  They are
then used by subsequent patch to implement conditions determining the
last iteration for the lastprivate OpenMP sharing clause.

Committed to the branch, queued for merge to trunk soon.
Thanks,

Martin

        * hsa-builtins.def (BUILT_IN_HSA_GRIDSIZE): New.
        (BUILT_IN_HSA_CURRENTWORKGROUPSIZE): Likewise.
        * hsa-gen.c (gen_hsa_insns_for_call): Handle BUILT_IN_HSA_GRIDSIZE.
