Okay, I pulled together a slightly more comprehensive report ... in
short, we pull things from everywhere. Maybe this is useful to someone
if they want to try and treeify the fallbacks :)

The format should be fairly self-explanatory. It is a rollup report
for all of the baselines, grouped on the combination of ports,
platforms, and type of baselines. The first column is the
port/platform configuration. The second is the location of the test
("generic" means not in a platform/* directory). The third is the type
of baseline for the test, the fourth is the location of the baseline
used, and the fifth is the total # of such baselines in that location.
