Summary
Fuzzer crash when parsing illegal memory instruction in WASM binary

If a WASM binary specifies no memories it is illegal to use any memory instructions. Currently if a load or store lives in an unreachable expression in a module with no memories it triggers a release assert instead of returning a parse error.
