  -----------
  [ConstraintElimination] Add Decomposition struct (NFCI)

Replace the vector of DecompEntry with a struct that stores the
constant offset separately. I think this is cleaner than giving the
first element special handling.

This probably also fixes some potential ubsan errors by more
consistently using addWithOverflow/multiplyWithOverflow.
