Read-only fallbacks (get_f64/bool/number, state, has, borrow) carry
memory(read, inaccessiblemem: readwrite) at the call site and the guard loads
the storage bases before branching, so LLVM hoists header loads out of
loops. Conditions on number[]/boolean[] element reads no longer box
T | undefined: numbers reuse getNumber (missing is NaN, falsy like undefined),
booleans test the slot state then read the value.
