Always include `liftcode` phase in a compiler run.

It turns out that `liftcode` phase must be always
executed or other phases will fail. Specifically,
at the moment `explicitouter` seems to depend on
`liftcode`. One can observe compiler crash by
compiling scala/Array.scala file without `liftcode`
included. At `explicitouter` phase compiler will
crash with assertion error saying it cannot
lift some code.
