Markus Schirp 13cd04d9be Introduce AST::Meta to externalize semantic analysis
* Add Mutant::AST namespace to hold all AST related data / helpers.
* Mutant::AST will be externalized into an ast-meta gem that can be
  shared with unparser for deduplication.
* Over the time the mutators itself will not need to deal with semantic
  analysis of the AST anymore by themselves.
* Move AST analysis for send nodes to AST::Meta
* Fix #209
