[cfe-commits] [PATCH] Teach printf warnings about small integer types.

[Justin Bogner]

Previously, the printf warnings would say your arguments type was
`int` when it was really a `char` or a `short`. This fixes that and
allows the hints to suggest `h` modifiers for small ints.

Typedef'd `char` types are treated as ints, since the most common case
of uint8_t shouldn't normally be formatted as a character.
