Clemens Hammacher be1a231625 [wasm][interpreter] Check signature before getting code
On indirect function calls, if the corresponding table entry is empty,
we cannot call {GetCodeFromStartAddress}. In that case, the signature
check will fail anyway, so perform the signature check first, and only
get the code object if the check succeeds.
