[PATCH] D48394: [WebAssembly] Error if mismatched function signture is includes in final output

During symbol resolution we emit warnings for function signature
mismatched.  During GC, if any mismatched symbol is marked as live
then we generate an error.

This means that we only bail out if the mitmatch would occur in the
final output.  i.e. if we would generate an invalid wasm file.
