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.
