Remove all #if 0'd code.
* filter.c: Remove #if 0'd function it_is. (main): Remove #if 0'd code. * gen-engine.c: Remove #if 0'd functions print_jump, print_jump_insn, print_jump_definition, print_jump_internal_function, print_jump_body. (gen_engine_c): Remove #if 0'd code. * gen-idecode.c: Remove #if 0'd functions print_jump print_jump, print_jump_insn, print_jump_definition, print_jump_internal_function, print_jump_until_stop_body. * gen-model.c: Remove #if 0'd functions model_c_or_h_data, model_c_or_h_function, gen_model_h, model_c_insn, model_c_function, gen_model_c and types model_c_passed_data and struct _model_c_passed_data. * gen.c: Remove #if 0'd type constant_field_types and function insn_field_is_constant. (gen_entry_find_opcode_field): Remove #if 0'd code. * ld-insn.c (parse_insn_model_record): Remove #if 0'd code. * misc.h (STRDUP, STRNDUP): Remove #if 0'd macros.
