Test Suite fails under -no-specialization

[scabug]

Resolution of this issue should also come with a -no-specialization nightly build.

• Check out https://github.com/lrytz/scala/tree/no-spec

• ant -Dlocker.skip=true -Dscalac.args="-no-specialization" -Dmaven.version.suffix="-nospec" -Ddocs.skip=1 publish-local

• Check out https://github.com/lrytz/scala-partest/tree/no-spec

• sbt publishM2

• Go back to the scala checkout

• ant -Dlocker.skip=true -Darchives.skipxz=true -Dscalac.args.optimise= '-Dscalac.args="-no-specialization"' '-Dpartest.scalac_opts="-no-specialization"' nightly

Log of failed tests below. At least some of them are due to #7481.
