Replaced LiftCode with a function in MacroContext

Major cleanup of reification:
* LiftCode phase has been removed
* Code has been deprecated and will be removed as we roll a new starr
* Logic related to type-directed lifting has been purged

scala.reflect.macro.Context#reify now provides the same services
as LiftCode provided (except that it returns Tree, not Code).

For testing purposes, I've retained the oh-so-convenient automagic lift.
test/files/codelib/code.jar now hosts Code.lift reimplemented in a macro,
so that the tests can continue working as if nothing has happened.
