// - C_TYPE_NAME is the name of the C type.

// - C_TYPE_BITWIDTH is the expected size of the C type; a zero value

// - SWIFT_MODULE_NAME is the name of the swift library module.
// - SWIFT_TYPE_NAME is the name of the corresponding stdlib type.
// - CAN_BE_MISSING is true if it is OK for swift type to be missing in the

// - C_NAME_MAPPING specifies if we should create a typealias in the
