Remove Java references in source code.

2017-07-14  Martin Liska  <mliska@suse.cz>

	* cfgexpand.c (expand_gimple_basic_block): Remove dead comment.
	* dwarf2out.c (is_java): Remove the function.
	(output_pubname): Remove usage of the function.
	(lower_bound_default): Remove usage of DW_LANG_Java.
	(gen_compile_unit_die): Likewise.
	* gcc.c: Remove compiler defaults for .java and .zip files.
	* gimple-expr.c (remove_suffix): Change as there's no longer
	extension than 4-letter one.
	* gimplify.c (mostly_copy_tree_r): Remove Java-special part.
	(gimplify_save_expr): Likewise.
	* ipa-utils.h (polymorphic_type_binfo_p): Remove the comment
	as it's possible even for other languages than Java.
	* langhooks.h (struct lang_hooks): Remove Java from a comment.
	* lto-opts.c (lto_write_options): Remove reference to Java.
	* opts.c (strip_off_ending): Update file extension handling.
	* tree-cfg.c (verify_gimple_call): Remove comment with Java.
	* tree-eh.c (lower_resx): Likewise.
	* tree.c (free_lang_data_in_type): Remove dead code.
	(find_decls_types_r): Likewise.
	(build_common_builtin_nodes): Remove Java from a comment.
	(verify_type): Remove dead code.
	* varasm.c (assemble_external): Remove Java from a comment.
