inconsistent code generation depending on use of -optimise

[scabug]

Problem exists in trunk, but not in 2.7.4. The basic idea is that if I have a library A that doesn't use -optimise, and then I build a library B that extends a trait in library A with class C, and library B does use optimize, then the generated code is wrong and fails at runtime.

If they're all compiled together, it doesn't seem to be a problem.

Steps:

  mkdir classes
  scalac -d classes Tensor.scala
  scalac -optimise -d classes DoubleCounter.scala
  scala -cp classes/
Welcome to Scala version 2.8.0.r0-b20090901205458 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_07).
Type in expressions to have them evaluated.

There's a good chance this example could be made more minimal, but I'm not sure.

(Also, can we please have an -optimize alias for -optimise. Ignorant Americans and such 😄
