<pre>
    The following pseudos do not have an explicit `hasSideEffects = 0` in the *.td files, so the MCInstrs are marked as `MCID::UnmodeledSideEffects`:
```
S_ADD_CO_PSEUDO
S_MUL_I64_I32_PSEUDO
S_MUL_U64_U32_PSEUDO
S_SUB_CO_PSEUDO
S_UADDO_PSEUDO
S_USUBO_PSEUDO
```
These are all regular ALU operations without side effects.
