ahaas 57b14b0606 [wasm] Track in the interpreter if a NaN could have been produced. ... The wasm specification does not fully specify the binary representation of NaN: the sign bit can be non-deterministic. The wasm-code fuzzer found a test case where the wasm interpreter and the compiled code produce a different sign bit for a NaN, and as a consequence they produce different results. With this CL the interpreter tracks whether it executed an instruction which can produce a NaN, which are div and sqrt instructions. The fuzzer uses this information and compares the result of the interpreter with the result of the compiled code only if there was no instruction which could have produced a NaN.
