- reduces _static_ callee saved register spills
  and restores similar to Chow's original algorithm.
- iterative implementation with simple heuristic
  limits to mitigate compile time impact.
- handles placing spills/restores for multi-entry,

  splitting edges.
- passes test-suite in LLCBETA mode.

Added contains() method to ADT/SparseBitVector.
