Remove junk from when gcc/java was created (by copying from C/C++).

	* decl.c (keep_next_level_flag, keep_next_if_subblocks):  Remove.
	(struct binding_level):  Remove fields keep, keep_if_subblocks,
	more_cleanups_ok, have_cleanups (which have never been used).
	(pushlevel, poplevel):  Remove related useless code.
