	* alias.c (find_base_decl): Remove unreachable case '3' block.
	* expr.c (safe_from_p): Abort if passed a type.
	* tree-gimple.c (recalculate_side_effects): Abort if passed
	anything other than an expression.
	* tree-ssa-pre.c (phi_translate): Return expr immediately if
	is_gimple_min_invariant is true for it.  Reorder cases for clarity.
	Abort on un-handled tree classes.
	(valid_in_set): Likewise.
	* tree.c (tree_code_class_strings): New static data.

	* tree.h (enum tree_code_class): New.
	(tree_code_class_strings): Declare.
	(TREE_CODE_CLASS_STRING, EXCEPTIONAL_CLASS_P, CONSTANT_CLASS_P)
	(REFERENCE_CLASS_P, COMPARISON_CLASS_P, UNARY_CLASS_P, BINARY_CLASS_P)
	(STATEMENT_CLASS_P, EXPRESSION_CLASS_P, IS_TYPE_OR_DECL_P): New macros.
	(TYPE_P, DECL_P, IS_NON_TYPE_CODE_CLASS, IS_EXPR_CODE_CLASS)
	(checking macros, EXPR_LOCATION, SET_EXPR_LOCATION, EXPR_LOCUS): Update.

	* tree.def, c-common.def, objc/objc-tree.def: Use
	tree_code_class enumeration constants instead of code letters.
