Log:
	PR sanitizer/70683
	* tree.h (inchash::add_expr): Add FLAGS argument.
	* tree.c (inchash::add_expr): Likewise.  If not OEP_ADDRESS_OF,
	use STRIP_NOPS first.  For INTEGER_CST assert not OEP_ADDRESS_OF.
	For REAL_CST and !HONOR_SIGNED_ZEROS (t) hash +/- 0 the same.
	Formatting fix.  Adjust recursive calls.  For tcc_comparison,
	if swap_tree_comparison (code) is smaller than code, hash that
	and arguments in the other order.  Hash CONVERT_EXPR the same
	as NOP_EXPR.  For OEP_ADDRESS_OF hash MEM_REF with 0 offset
	of ADDR_EXPR of decl as the decl itself.  Add or remove
	OEP_ADDRESS_OF from recursive flags as needed.  For
	FMA_EXPR, WIDEN_MULT_{PLUS,MINUS}_EXPR hash the first two
	operands commutatively and only the third one normally.
	For internal CALL_EXPR hash in CALL_EXPR_IFN.
