Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):

Add support of tuple argument to argMin and argMax functions.

Detailed description / Documentation draft:

This commit adds support of tuple argument (with two elements) to argMin and argMax functions, and for this kind of calls changes return value to the tuple too. This allows to use them in SimpleAggregateFunction, since the tuple works as a state. Also could be useful for discovering maximum and minimum values from comparisons.

@Avogar hi, could you look at ClickHouse/dragonbox#2? I suspect that build errors are related with dragonbox.

Hi, I don't have rights to merge PR in ClickHouse-Extras, you can ask @alexey-milovidov. I had a look at build errors, it seems that splitting argMin(Max) creators to separate file was not enough and the translation unit is still too large. May be you can try to simplify it somehow?

[ildus]

I tried to run the failed command locally and the build failed on dragonbox. Just wanted to check it first. The simpilfying also makes sense, I'll look into it.

@Avogar Eventually I removed using templates for the tuple argument, and have added extracting of columns on addBatch* level, this gives almost same performance as with usual columns, but with the price of more code.

Thanks!
