2764fd8d1a Steps towards unification of number bitset and range types. 
- New invariant on union types: if the union has a range then the number
  bits in the bitset must be cleared.

- Various tweaks in intersection and union to satisfy the invariant.

- Exposed and used representation bits in range types (and the Limits
  helper class).

- Implemented Glb for ranges so that the Is predicate handles
  ranges correctly.

- Change typer weakening so that it does not rely on GetRange.
  However, the code still seems to be a bit fragile.

- Removed the Smi types from the type system core, instead introduced
  Signed31, Unsigned30 and created constructors for Small(Un)Signed
  that point to the right type for the architecture.

- Punched a hole in the config to be able to get to the isolate so
  that it is possible to allocate heap numbers for newly created
  ranges.

  Fix issue with __proto__ when using ES6 object literals

  It should be possible to create a concise method with the name
  __proto__ without setting the [[Prototype]]. Similarly, property
  name shorthands with the name __proto__ should define an own

feffccca22 Profiler improvements 
(1) --prof-cpp: Collects ticks like --prof, but ignores code creation events to reduce distortion (so all JS ticks will be "unaccounted"). Useful for profiling C++ code.
(2) --timed-range flag for tick processor: Ignores ticks before the first and after the last call to Date.now(). Useful for focusing on the timed section of a test.
