std::int::min_value, max_value, etc. should be capitalized

Not sure why they are lowercase.

@berleon, are you still working on this? I'll be happy to pick up where you left off.

@lfairy Have a go at it.

@brson I've noticed in std::char, the constant is named simply MAX, with no _VALUE suffix. Should I match this convention?

Now that I think about it, I prefer the shorter MIN and MAX actually. They'll end up referred as e.g. int::MAX, which looks a lot like INT_MAX in C. I think the main reason we kept the suffixes was to prevent confusion with the min and max functions; capitalizing the constants makes this a non-issue.
