rL357531: [libc++] Fix error flags and exceptions propagated from input stream operations
Summary

Before this patch, we would only ever throw an exception if the badbit
was set on the stream. The Standard is currently very unclear on how
exceptions should be propagated and what error flags should be set by
the input stream operations. This commit changes libc++ to behave under
a different (but valid) interpretation of the Standard. This interpretation
of the Standard matches what other implementations are doing.

I will submit a paper in San Diego to clarify the Standard such that the
interpretation used in this commit (and other implementations) is the only
possible one.

This is a very tricky change since it touches all the input stream operations, both formatted and unformatted. However, I think it's an important change as it fixes extremely broken behavior. The paper I'm working on to fix this in the Standard is https://github.com/ldionne/wg21/blob/4d963b488182b96479636c252695542671fd5e41/generated/drxxxx.pdf. Perhaps we should wait for the paper to make its way through the Standard before committing this, but in any case the new behavior of libc++ should now match that of libstdc++ and MSVC (couldn't test with those libraries, though).

I would like to merge this even though http://wg21.link/p1264 has not been voted into C++ yet, because this is arguably a bug and libc++ differs from other stdlibs in this regard. Once http://wg21.link/p1264 is merged into C++ in one way of another, libc++ will simply have nothing to do.

@mclow.lists Are you OK with that?

I'm OK with this. I think, strictly speaking, that libc++ is following the standard, and everyone else is not - but what everyone else is doing makes sense.

It looks like this may have broken some LLDB data formatters:

I reverted in r357536 to give some time to figure what the problem is.

It turns out I think only r357531 had been applied and this is what broke the LLDB CI.

Hi @ldionne, you're setting the local __state and returning, while before we calling this->setstate.
I see you added this->setstate(__state); in the bottom.
It seems this is a bug?

@ldionne, another dubious aspect of this patch is that it initializes __r to 0 and never sets it. Seems like this line should have been to set __r and not to return directly.
