class.c (assume_compiled_node_struct): Rename type to class_flag_node_struct, as it is now also used for enable_assertions.
* class.c (assume_compiled_node_struct): Rename type to
class_flag_node_struct, as it is now also used for enable_assertions.
Rename assume_compiled_node typedef. Rename excludep field to value.
(find_assume_compiled_node): Rename function to find_class_flag_node.
Minor optimization - avoid needless strlen.
(add_assume_compiled): Some tweaking and optimization.
Rename and generalize to add_class_flag takem an extra parameter.
(add_assume_compled): New just calls add_class_flag.
(add_enable_assert, enable_assertions): New functions.
(enable_assert_tree): New static.
* java-tree.h (add_enable_assert, enable_assertions): New declarations.
* lang.opt (fenable-assertions, fenable-assertions=,
fdisable-assertions, fdisable-assertions=): New options.
* lang.c (java_handle_option): Handle new options.
* parse.y (build_incomplete_class_ref): Handle class$ in an inner
class in an interface - create helper class nested in outer interface.
(build_assertion): Short-circuit if enable_assertions is false.
