Currently, when a kernel is lauched with too many workers, it results in a cuda
launch failure. This is triggered f.i. for parallel-loop-1.c at -O0 on a Quadro
M1200.
This patch detects this situation, and errors out with a hint on how to fix it.
Build and reg-tested on x86_64 with nvptx accelerator.
