openmp: Handle even some combined non-rectangular loops
The number of loops computation and logical iteration -> actual iterator values
computations can now be done separately even on composite constructs (though
for triangular loops it would still be more efficient to propagate a few values
through, will handle that incrementally).
simd and taskloop are still unhandled.

* omp-expand.c (expand_omp_for): Don't disallow combined non-rectangular
loops.
* testsuite/libgomp.c/loop-22.c: New test.
* testsuite/libgomp.c/loop-23.c: New test.
