Known nvfortran 25.3 defects

• select rank does not compile, and a bind(C) dummy procedure is called wrongly, so the code selects among specific procedures instead.
• -O2 miscompiles the step function of tandem_rng_target when it updates the elements of its h(4) argument in place, in offloaded code only. It uses scalar temporaries instead.
• c_loc and c_devloc of an assumed-rank argument of rank 2 and up return the address of the element at index zero in every dimension, not of the first element. With its GPU flags, a C descriptor of the argument is wrong too. The device array fills therefore have one specific per rank, and the host fills of rank 2 and up stop with an error under nvfortran. Fill a rank 1 pointer to the array there, p(1:size(a)) => a.
