Various optimizations

Various optimizations

• optimize interface dispatch implementation (interface template)
• optimize external call routines
• optimize equal generic implementation (in basic module)
• optimize wideConvertor / literalConvertor
• optimize CallStack
• optimize - if (0 == theTop) (where theTop is ref)
• optimize TextBuilder
• optimize anagram sample, after recent changes it is slowed down
• opimized alt operator implementation : resolve it in compile-time if the operand is known
• optimize using, finally, try template implementations (get rid of dynamic closures)
• optimize listof.setAt&int$&object[2]: there should be primitive comparison operation
• optimize listof.$expand
• optimize ArrayList / list template insert operation (use xset for moving the references rather than set)
• optimize multimethod implementation for sealed class containing only one overload class
• external function : duplicate assigning
• do not allocate a virtual vmt (for the object initilizer code)
• redesign mtredirect / xmtredirect, for three, four parameters (?)
• mtredirect / xmtredirect : do not need to save ecx twice
