Toon Verwaest a5f559c3f8 [parser] Change how catch is parsed 
- Directly declares the special catch variable from the parser-base.
- Tracks Scope on PreParserBlock and finds conflicting lexical declarations by
  simply walking the VariableMap of the block inserted for the pattern; or the
  catch variable in case of identifier.
- This also enables throwing errors for duplicate let in the preparser. We may
  have to back that out if it breaks something.
