Member predicate IntegralType::getCanonicalArithmeticType

Gets the canonical type corresponding to this integral type.

For a plain type, this gives the same type (e.g. short -> short). For an explicitly unsigned type, this gives the same type (e.g. unsigned short -> unsigned short). For an explicitly signed type, this gives the plain version of that type (e.g. signed short -> short), except that signed char -> signed char.
