Fix bugs for static fields/blocks and instanceof operation. To effectively support static fields/blocks, we need to generate a special version for methods that could be invoked in static blocks or when initializing static fields. In the special version, if there are classes with static fields/blocks are involved, we'll check if the static fields have been initialized and if the static blocks have been executed. Previously we misused C micros to implement this(MGC_STATIC_INIT_CHECK). Now we remove this wrong macro and generate the required special version. For instanceof operation, we fix two bugs. One is that previously we did not take interfaces into consider and the other is that in the instanceof(struct Object *, int) function we did not check if the Object is NULL or not. If the Object is NULL, we shall always return false.

Fix a shadow field related bug in the compiler. Defined in Java language specification, if the class declares a field with a certain name, then the declaration of that field is said to hide any and all accessible declarations of fields with the same name in superclasses, and superinterfaces of the class. However, the hidden fields in superclasses or superinterfaces can still be accessed by using a qualified name (if it is static) or by using a field access expression that contains the keyword super or a cast to a superclass type. Previously, our compiler simply discarded all the hidden fields so that the hidden fields can never be accessed. Now we maitain all the fields including the hidden ones. We prefix the name of the class that defines the field to the field's name to differentiate the shadow field and the hidden fields. Some of the hard coded fields dereference in the Runtime C code are fixed accordingly. Now the unit tests, multicore benchmarks and oooJava related benchmarks are checked to be OK. But (D)STM related Runtime code are NOT checked yet.
