That way we will know if this is what fails.
so we know which one triggers the illegal memory access

This PR adds a CUDA call tracer. The main purpose of the tracer is to hopefully help debug the illegal memory access crashes reported in #398 and #425. If there is a crash, the last 32 invocations of
CUDA_CHECKwill be printed tostderrbefore aborting. In my testing the overhead added by the tracer has negligible impact on performance.
