  Log Message:
  -----------
  [ConstraintElimination] Refactor constraint extraction (NFC).

This patch generalizes the extraction of a constraint for a given
condition. It allows decompose to return a vector of c * X pairs, which
allows de-composing multiple instructions in the future.

It also adds more clarifying comments.
