A huge -Wmax-wasm-stack crashes the CLI, because deriving the async stack size from it overflows,
while zero is already rejected with a clear error.

A huge -Wmax-wasm-stack crashes the CLI, because deriving the async stack size from it overflows,
while zero is already rejected with a clear error. Such a value still fails later on a 32-bit
target, when the stack it asks for cannot be allocated -- that is how Store::new already behaves.

@alexcrichton It has been re pushed. The failure of i686 is a testing issue, not a repair issue. 32-bit cannot allocate this stack
