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