ORC-1146: Float category missing check if the statistic sum is a finite value

[guiyanakuang]

What changes were proposed in this pull request?

This pr is aimed at checking whether the float category statistic sum has a finite value.

Why are the changes needed?

When the orc float category is written with NaN, pushing down is not supported.

How was this patch tested?

Added unit test.

I deleted my previous comment about the branch-1.7 test result.

At a clean build, I verified this patch in branch-1.7 and backported. Thank you again, @guiyanakuang .

Could you re-run your integration tests, @williamhyun ?

[dongjoon-hyun]

BTW, @guiyanakuang . Could you check branch-1.6 too when you have a time? We backported the following in branch-1.6. I guess we might have the same issue there.

• ORC-1121: Fix column coversion check bug which causes column filters don't work #1055

Thanks @dongjoon-hyun . I checked the branch-1.6 and confirmed it has the same problem. This pr can just cherry pick and fix it without any conflicts.
Later on I will also commit an improvement to determine the presence of NaN writes, which I think can also be ported backwards to 1.6. 😄
