Do not use exported memory as a root set of RemoveUnusedFunctions pass (#763)
* Do not use exported memory as a root set of RemoveUnusedFunctions pass
RemoveUnusedFunctions pass of wasm-opt fails when the memory is exported.
That's due to a wrong root set handling on the exported symbols.
This CL fixes the failure by ignoring non-function exported symbol.
