(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.

Fix dictionary element load to pass correct elements kind.

Using FAST_SMI_ELEMENTS triggers optimization on 64-bit architectures that load
only the higher 32 bits of the element. If the element is a pointer to undefined
that has 0 in the higher half than it is erroneously treated as SMI 0.

MIPS: Fix assignment of function name constant.

Port r19379 (622d830)

Original commit message:
If it's shadowed by a variable of the same name and both are forcibly
context-allocated, the function is assigned to the wrong context slot.
