[vm/compiler] Bug fix in 64-bit MOD (%) operator.

Rationale:
While writing tests for the ongoing native 64-bit
MOD/TRUNCDIV support in AOT, I noticed a floating-point
crash in our VM due to evaluating the constant mod case:

  Expect.equals(0, mod(minInt64, -1));
  Expect.equals(minInt64, truncdiv(minInt64, -1));

This fixes the constant evaluation part.
