Refactoring: moved the 'isNaN', 'isPositiveInfinity' and 'isNegativeInfinity' to the 'CDebugUtils' class.
* ICValue.java
* CValue.java
* CDebugUtils.java
2003-07-28 Mikhail Khodjaiants
Refactoring: moved the 'CDebugUtils' class to the 'org.eclipse.cdt.debug.core' package -
the methods of this class are mostly used in UI plugins.
