73c4a61848 (Pre)Parser: Simplify NewExpression handling (fixed). 
Notes:
- We use simple recursion to keep track of how many "new" operators we have seen

- This makes the self-baked stack class PositionStack in parser.cc unnecessary.
- Now the logic is also unified between Parser and PreParser.

429ce41f4b Make a single HeapEntry per single JSArrayBuffer data in heap snapshot. 
It turned out that JSArrayBuffer's may share their backing_store so
the backing_store should go through hash map registration just like
other heap objects, so they won't be reported twice.

1634631ae4 A64: Tidy up Push and Pop TODOs. 
This addresses several TODOs:
  - Push and Pop requests can be queued up so that arrays of Registers
    can be pushed efficiently, with just one PrepareForPush/Pop.
  - PushMultipleTimes now takes an Operand. This allows variable-length
    arguments arrays to be initialized, for example.
  - A NoUseRealAbortsScope has been added to Abort so that
    AssertStackConsistency can be called from PrepareForPush without
    introducing infinite recursion.
