[PATCH] Minor cleanups

[Richard Biener]

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

2014-04-15  Richard Biener  <rguenther@suse.de>

	* tree.c (iterative_hash_expr): Use enum tree_code_class
	to store TREE_CODE_CLASS.
	(tree_block): Likewise.
	(tree_set_block): Likewise.
	* tree.h (fold_build_pointer_plus_loc): Use
	convert_to_ptrofftype_loc.
