Antonio Sanchez 16f9a20a6f Add buildtests_gpu and check_gpu to simplify GPU testing.
This is in preparation of adding GPU tests to the CI, allowing
us to limit building/testing of GPU-specific tests for a given
GPU-capable runner.

GPU tests are tagged with the label "gpu".  The new targets
```
make buildtests_gpu
make check_gpu
```
allow building and running only the gpu tests.
