10// This file implements sparse conditional constant propagation and merging:
11//
12// Specifically, this:
13// * Assumes values are constant unless proven otherwise
14// * Assumes BasicBlocks are dead unless proven otherwise
15// * Proves values to be constant, and replaces them with constants
16// * Proves conditional branches to be unconditional
