Fix Eigen's building of sharded tests that use CUDA & more igamma/igammac bugfixes.
...
0. Prior to this PR, not a single sharded CUDA test was actually being *run*.
Fixed that.
GPU tests are still failing for igamma/igammac.
1. Add calls for igamma/igammac to TensorBase
2. Fix up CUDA-specific calls of igamma/igammac
3. Add unit tests for digamma, igamma, igammac in CUDA.
