Exposes IsReverseDims in BlockInfo

related to request in #1553 from @berkgeveci

I guess a general comment is that since IsReverseDims will always be the same across all blocks in a Variable, I'd prefer to have it exposed on a per-Variable basis, not per-Block. Most readers / viz apps will probably not naturally use the block-based API.

minor comment: dims may also have been swapped from row-major to col-major, when reading from Fortran.

@germasch this particular struct is only exposed in the C++11 bindings

[williamfgc]

@germasch see my comment in #1553, it's not unreasonable to think we might need this info on a per block basis. The block inspection functions in C++ were designed with in-situ viz as one of the use-cases. It's very much needed.

See #1553 (comment)

I don't want to push this in the release. We need some time to get it right and work with the apps that need it (both vis and simulations). It's a new feature with only a day left to the release. Let's go ahead and put this in master instead for now so it will be there but still give us time to refine it for the next release.

[chuckatkins]

@williamfgc please edit the PR to target master instead. If we want to put out a patch release soon after with this then we can. For now though, given the short time frame, let's keep it out of the release.

Moving to master

@chuckatkins fine with me, just doing this for you and @berkgeveci
