re PR rtl-optimization/17236 (inefficient code for long long multiply on x86) 

	PR rtl-optimization/17236

	from expand_binop.  Permute the order in which instructions are
	emitted to minimize the number of simultaneously live registers.
	(expand_binop): Call expand_doubleword_mult to synthesize a double
	word multiplication.
