[Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>]

From: Bernhard Reutner-Fischer <aldot@gcc.gnu.org>

gcc/rust/ChangeLog:

	* backend/rust-compile-expr.cc (CompileExpr::type_cast_expression): Use
	_P() defines from tree.h
	* backend/rust-tree.cc (build_cplus_array_type): Ditto.
	* backend/rust-tree.h (ARITHMETIC_TYPE_P): Ditto.
	(gnu_vector_type_p): Ditto.
	* checks/lints/rust-lint-unused-var.cc (check_decl): Ditto.
	* rust-gcc.cc (Gcc_backend::fill_in_array): Ditto.
	(Gcc_backend::named_type): Ditto.
	(Gcc_backend::convert_expression): Ditto.
	(Gcc_backend::init_statement): Ditto.
