Description:
(Pre)Parser: Simplify NewExpression handling.
Notes:
- We use simple recursion to keep track of how many "new" operators we have
seen
and where.
- This makes the self-baked stack class PositionStack in parser.cc
unnecessary.
- Now the logic is also unified between Parser and PreParser.
- It might have been a copy-paste artifact (ParseLeftHandSideExpression ->
ParseMemberWithNewPrefixesExpression) that the logic was so complicated
before.
