Merge pull request #55 in G/fastr from ~STEPAN.SINDELAR_ORACLE.COM/fastr:GR-131-remove-rfactor to master

* commit 'd66555f1':
  Remove remaining RFactor references.
  Remove creation of RFactor, fix failing tests
  supply proper TypeSystemReference in AsVectorInternal
  proper internal generic dispatch in as.vector
  RAttributable has default method getAttr

Plus few new tests. BinaryBooleanNode: not the most optimal code for factors,
but factor specialization should be removed and dispatched to their R code.

This commit removes the creation of RFactor, but not the class itself yet,
and fixes all the failing tests. However, not all factors references are
removed yet. Note: there is one failing test due to issues in do.call
implementation.

Method getAttribute removed from RAttributeStorage and
its usages updated to getAttr. Name of getAttr reflects
another pre-existing overload of this method in RAttributable.

  Commit ff587828f2aa04feb043276dcd05d8d4a56047f7  (2016-04-05) in graal-core removed the compile() method from GraalTruffleRuntime.java, resulting in the error "FastR internal error: fastr.compile: failed to find 'compile' method" when trying to run FastR with Graal. This change uses the new submitForCompilation and finishCompilation methods. Note that finishCompilation is called so that notifyCompilationQueued is called, see e.g. similar usage in OptimizedCallTarget.java: compile().
