Merge pull request #133 in G/fastr from ~LUKAS.STADLER_ORACLE.COM/fastr:bugfix/S3_lookup_order to master

* commit '16575993':
  change S3 lookup order to consider enclosing env and method table simultaneously

Merge pull request #134 in G/fastr from ~STEPAN.SINDELAR_ORACLE.COM/fastr:bugfix/print-recursive-attrs to master

* commit 'b5ee0472':
  Fix: printing lists stored in attributes of another list

Merge pull request #130 in G/fastr from ~STEPAN.SINDELAR_ORACLE.COM/fastr:feature/args-matching to master

* commit '9f363be5':
  Removed formal signature from frame slots operated by RArguments
  S3 dispatch fixed to do correct args matching after UseMethod

Merge pull request #132 in G/fastr from ~LUKAS.STADLER_ORACLE.COM/fastr:feature/rename_output_containserror to master

* commit 'bee7eb99':
  fix formatting problem
  rename ContainsError and ContainsWarning in TestRBase as well
  rename ContainsError to IgnoreErrorContext, etc.

Merge pull request #135 in G/fastr from ~LUKAS.STADLER_ORACLE.COM/fastr:feature/substitution_refactoring to master

* commit 'ff79d695':
  substitution based on RASTBuilder instead of implementations in RSyntaxNode subclasses

Merge pull request #131 in G/fastr from ~LUKAS.STADLER_ORACLE.COM/fastr:bugfix/parser_errors to master

* commit '711c6f88':
  do not throw RErrors created during parsing through PolyglotEngine

Merge pull request #129 in G/fastr from ~LUKAS.STADLER_ORACLE.COM/fastr:bugfix/use_virtual_eval_frame_profile to master

* commit '26e5563d':
  use the profiling VirtualEvalFrame subclasses in a proper way

ArgumentMatcher returns supplied signature permuted in the
same way as the supplied arguments. This is stored in frame
using RArguments for accessing this info through getSuppliedSignature().
UseMethod then uses getSuppliedSignature instead of RArguments.getSignature.

* commit '5d66fafd':
  remove obsolete comment
  keep better names for functions during code duplication in RASTBuilder
  simplification in WrapDefaultArgumentNode
  only use one type of inline cache in PromiseHelperNode
  simplify ArgumentsStatePush
  unwrap promises for stable lookups in FrameSlotChangeMonitor
  small simplification in ReadVariableNode
  refactor Missing to not use the generic inline cache node
  improve Transpose (better treatment of attributes)
  remove TruffleBoundaries in Transpose
  refactor MersenneTwister

* commit 'c731a8e1':
  introduce and use createSharedXyzVectorFromScalar functions
  make usages of ROptions.getValue able to deal with scalar values
  makeSharedPermanent should return "this"
  populate ROptions with primitives instead of non-shared vectors
  enable passing tests
  move gpbits functions into RBaseObject
  decide printing of S4 objects similar to GNUR
  less output on ProcessFailedTests
  cleanups
  make "names" internal generic
