Remove last use of expr_align

It was in the ada/gcc-interface repository and is outdated.

	* tree.h (expr_align): Delete.
	* tree.c (expr_align): Likewise.
ada/
	* gcc-interface/utils2.c: Include builtins.h.
	(known_alignment) <ADDR_EXPR>: Use DECL_ALIGN for DECL_P operands
	and get_object_alignment for the rest.
