[nomaster] run mima both ways, filter out failures

Using @gkossakowski's contribution to mima (in 0.1.5-SNAPSHOT),
make sure bc.run doesn't fail by filtering out all binary incompatibilities.

Each subsequent commit will comment out the filters it makes irrelevant,
until we only need to filter out permitted binary incompatibilities.

We only allow binary incompatibilities in scala.reflect.internal.
