By lowering the size of the shared memory, we ensure that it is always
less than MAX_ARRAY_BUFFER_SIZE (0x7fffffff on 32-bit).

Wabt's wasm2wat and wat2wasm were used to disassemble and reassemble
only-referenced.wasm.

* JSTests/wasm/stress/only-referenced.js: Only skipp if platform does
  not support wasm or we're running in memory limited mode
* JSTests/wasm/stress/resources/only-referenced.wasm: Lower size of
  shared memory
