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.

Revert of [turbofan] Fix bunch of tests failing with --turbo-deoptimization. (patchset #1 id:1 of https://codereview.chromium.org/786333004/)

Reason for revert:
This changes layout test expectations. I ran a bisect over the layout tests:

Bad:

Good:

If this is intentional please first land a CL with manualrebaseline test expectations for the changed tests and then reland.

Vector-based KeyedLoadIC MISS logic needs improvement.

Two issues:
1) We would trace the MISS two times on vector-based KeyedLoadIC
   with a string key in MEGAMORPHIC state.
2) There was a confusing asymmetry in the handling of going
   GENERIC. This change makes it the same whether
   --vector-ics is on or not.
