Here's a first set of changes to migrate the code base to the L/Q model again.
Changes are in the runtime, the interpreter, CI and C1.
The changeset also activates the mode in javac that generates a single class file per primitive class (instead of two).
Changes allow a reasonable number of test in runtime/valhalla/inlinetypes to pass with -XX:TieredStopAtLevel=1 but some tests are failing, mainly because of missing changes in array code and C2.
