 ;;; Test atomic swap for all types and all memory order
 ;;;
 ;;; Note:
 ;;;   - We test i1/i8/i16/i32/i64/i128/u8/u16/u32/u64/u128.
 ;;;   - We test relaxed, acquire, and seq_cst.
 ;;;   - We test only exchange with variables since VE doesn't have exchange
 ;;;     instructions with immediate values.
 ;;;   - We test against an object, a stack object, and a global variable.
