Another 600 redundant decl warnings zapped, down to ~4400.
Installed as obvious after bootstrapping passed on solaris2.7.

* c-common.h (truthvalue_conversion, type_for_mode,
type_for_size): Delete redundant declarations.
* c-lex.h (is_class_name): Likewise.
* c-tree.h (pedantic, convert, getdecls, gettags,
global_bindings_p, init_decl_processing, insert_block,
maybe_build_cleanup, poplevel, print_lang_decl,
print_lang_identifier, print_lang_type, pushdecl, pushlevel,
set_block, incomplete_type_error, build_function_call,
lvalue_or_else, mark_addressable): Likewise.
* expr.h (expand_tree_builtin): Likewise.
