This makes all union test cases succeed. `rem` was also implemented as all we had to do is enable the instruction. Loading and storing values based on ABI-size was simplified to a direct abiSize() call. We also enabled all the newly passing test cases and disable them for all non-passing backends. All of those test cases were verified to see if they perhaps already pass for the c-backend.
