re PR java/18305 (Class initialization optimization is not done when compiled from .class)

2004-11-26  Andrew Pinski  <pinskia@physics.uc.edu>

        PR java/18305
        * decl.c (end_java_method): Call
        attach_init_test_initialization_flags on all the init_decls.
        * parse.y (attach_init_test_initialization_flags): Move to ...
        * expr.c (attach_init_test_initialization_flags): here and
        support BIND_EXPR also.
        * java-tree.h (attach_init_test_initialization_flags): Prototype.
        * jcf-parse.c (parse_class_file): Don't disable class init
        optimization.
