Issue #1285 - implement named capturing groups and named backrefs

- RegExpParser collects seen groups in named_captures_.
- After irregexp::ParsePattern has finished, RegExpParser::StoreNamedCaptureMap translates
  the parser data to RegExpCompileData.capture_name/index
- RegExpShared::initializeNamedCaptures takes these and builds a PlainObject map which
  is kept with the compiled expression
This is done because irregexp doesn't have access to the JS context and so can't allocate
any JSValues itself.
- for each match result, this map is used to build PlainObjects of name->match/undefined
  (extremely simplified from upstream at the expense of some perf)

IonMonkey switches to non-masm code path for expressions with named groups.
