Compiler crashes when output directory doesn't exist

[vsalvis]

To reproduce, delete dotty/out and run the JUnit tests with test-only dotc.tests

The first few pos tests fail with java.io.IOException: No such file or directory. Then dotc.tests.dotc_core somehow creates the output directory again, from which point the tests pass.

scalac doesn't. Should Dotty?

dark@reco /tmp/t $ ls -la

dark@reco /tmp/t $ scalac A.scala -d out
scalac error: out does not exist or is not a directory
  scalac -help  gives more information

I misunderstood before. Greed this need not be required for dotty.
