// Atomic(bool) — a sub-byte (i1) element atomically loaded/stored. LLVM
// rejects a sub-byte atomic ("atomic memory access' size must be byte-
// sized"), so codegen performs the access in the byte storage type (i8)
// and trunc/zext's the value at the boundary. (rmw/cmpxchg on a bool is
// rejected at the sx level — integer-only — so only load/store apply.)
// Regression (issue 0152): Atomic(bool) emitted an i1 atomic that failed
// LLVM verification; Future.canceled: Atomic(bool) in the async layer hit it.
