Fix 2 binary fuzz bugs (#1323)
* Check if there is a currFunction before using it (we need it for some stacky code; a valid wasm wouldn't need a function in that location anyhow, as what can be put in a memory/table offset is very limited).
* Huge alignment led us to do a power of 2 shift that is undefined behavior.
Also adds a test facility to check we don't crash on testcases.
