// Taking the address of a scalar `::` constant is a compile error: a scalar
// constant folds to its value and has NO storage (only array/struct constants
// are immutable globals with a real address — see 0177). Covers a module-scope
// const, a local const, and an inline-asm `-> @const` write-through (the path
// that surfaced the bug). Before the fix, `@N` lowered to `inttoptr (i64 40 to
// ptr)` — a wild pointer that segfaulted on deref and emitted invalid stores
// for asm `-> @const`. Regression (issue 0138).
