java-interp.h (_Jv_LocalVarTableEntry): Add union for bytecode_pc and direct-threaded pc.

Browse source 
* include/java-interp.h (_Jv_LocalVarTableEntry): Add union
        for bytecode_pc and direct-threaded pc.
        Add field descriptions inline.
        * defineclass.cc (read_one_code_attribute): Change from
        bytecode_start_pc to bytecode_pc.
        Remove unused variable "len".
        * interpret.cc (compile): Remap the variable table, too.
        (get_local_var_table) [DIRECT_THREADED]: Use insn_index on the
        start location to map from pc_t to code index.
