Used to test specialization and deoptimization. This annotation works in conjunction with DeoptTest. The purpose of these annotations is to test specialization and deoptimization without the need of runtime compilation (which makes things a lot faster).

Use Specialize on methods which call DeoptTest methods. The arguments of the calls must evaluate to constants and they define the specialization of arguments.

Note that there may not be more than one call from a Specialize method to a DeoptTest method.
