It is used only on the lines below - 10632 & 10634, so I think it is good to 
keep its scope small. And not hoisting is consistent with other places using 
lambdas close to their 2 calls like different kinds of `PopulateHashes`.

This is a good observation. I've checked the usage of other hoisted lambdas and 
`ComputeTemplateParameterListODRHash` is used only in 2 places, so now I think 
we shouldn't hoist it.
