* gimplify.c (gimplify_omp_taskloop_expr): New function.
(gimplify_omp_for): Use it. For OMP_FOR_NON_RECTANGULAR
loops adjust in outer taskloop the var-outer decls.
* omp-expand.c (expand_omp_taskloop_for_inner): Handle non-rectangular
loops.
(expand_omp_for): Don't reject non-rectangular taskloop.
* omp-general.c (omp_extract_for_data): Don't assert that
non-rectangular loops have static schedule, instead treat loop->m1
or loop->m2 as if loop->n1 or loop->n2 is non-constant.
* testsuite/libgomp.c/loop-22.c (main): Add some further tests.
* testsuite/libgomp.c/loop-23.c (main): Likewise.
* testsuite/libgomp.c/loop-24.c: New test.
