Compilers

9 compiler releases from 4 families, each run on the GPUs listed with it. A release shows the issues that fail on it, split by when they fail; a part of a bar opens those issues in the list. Bars share a scale within each family only: the counts follow how hard each compiler was searched, not how good it is.
