Added lit-test, did some more cleanup.

Suggesting following commit message:

  [NPM] Added opt option -print-pipeline-passes.
  
  Added opt option -print-pipeline-passes to print a -passes compatible
  string describing the built pass pipeline.
  
  As an example:
  $ opt -enable-new-pm=1 -adce -licm -simplifycfg -o /dev/null /dev/null -print-pipeline-passes
  verify,function(adce),function(loop-mssa(licm)),function(simplifycfg<bonus-inst-threshold=1;no-forward-switch-cond;no-switch-to-lookup;keep-loops;no-hoist-common-insts;no-sink-common-insts>),verify,BitcodeWriterPass
  
  At the moment this is best-effort only and there are some known
  limitations:
  - Not all passes accepting parameters will print their parameters
    (currently only implemented for simplifycfg).
  - Some ClassName to pass-name mappings are not unique.
  - Some ClassName to pass-name mappings are missing (e.g.
    BitcodeWriterPass).
