[GlobalISel] Combine (G_*ADDO x, 0) -> x + no carry out
Similar to the G_*MULO change.
The code for checking if a constant is legal/pre-legalize is shared between
these, and is kind of hairy. So, factor it out into a new function:
`isConstantLegalOrBeforeLegalizer`.
To make the refactoring clean, further refactor `isLegalOrBeforeLegalizer` into
a wrapper for two functions:
- `isPreLegalize`
- `isLegal`
This is a bit easier to read in general.
