* The Compiler class is provided to support

* Compiler class does nothing; it serves as a
* placeholder for a JIT compiler implementation.
*
* When the Java Virtual Machine first starts, it determines if the
* system property java.compiler exists. (System
* properties are accessible through getProperty and,
* a method defined by the System class.) If so, and the
* name isn't NONE or none, the internal JIT is enabled.
*
* If no compiler is available, these methods do nothing.
