Removed unused imports.

A dizzying number of unused imports, limited to files
in src/compiler. I especially like that the unused import
option (not quite ready for checkin itself) finds places
where feature implicits have been imported which are no
longer necessary, e.g. this commit includes half a dozen
removals of "import scala.language.implicitConversions".
