Fixed PPCCompiler: must refetch class afer updating instance variables of a given class. The reason is, that in (at least) Smalltalk/X modyfing a layout of a class results in creating a new class rather than updating an old one and migrating instances, i.e., the old class is not identical with the new class. Therefore, to install methods in in correct class, we have to refetch new version from system dictionary. On Pharo it should not harm
