//  - C_TYPE_NAME is the name of the C type.
//  - C_TYPE_KIND is the expected kind of the C type (see MappedCTypeKind
//    enum).
//  - C_TYPE_BITWIDTH is the expected size of the C type; a zero value
//    means "don't check".
//  - 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
//    stdlib.
//  - C_NAME_MAPPING specifies if we should create a typealias in the
//    imported Clang module (see MappedTypeNameKind enum).
