Diego Novillo
c75704ec08 CFG cleanup pass - Remove unreachable blocks. 
- Adds a new pass CFGCleanupPass.  This serves as an umbrella pass to
  remove unnecessary cruft from a CFG.
- Currently, the only cleanup operation done is the removal of
  unreachable basic blocks.
- Adds unit tests.
- Adds a flag to spirvopt to execute the pass (--cfg-cleanup).
