Craig Topper 84d62ce6c1 [CostModel][X86][AArch64] Adjust cost of the scalarization part of min/max reduction. 
Summary: The comment says we need 3 extracts and a select at the end. But didn't we just account for the select in the vector cost above. Aren't we just extracting the single element after taking the min/max in the vector register?
