I'm not sure about this. I'm curious about we just consider any integer with
width less than or equal to `int` may be specified by `%hhd` ? (Because of
default argument promotions). For example, we may expect `%hhd` could accept
`int` `short` and `char`. And give diagnostics like
format specifies integers with width less than or equal to 'int', but the
argument has type 'double' (promoted from 'float')

OpenCL seems to defined a series of length modifiers for vectors, Is it more
reasonable to consider `hh` as fixed length (char) only? Because vectors are
passed without argument promotions.
