      [turbofan] Rework Node guts to save space. · 65b66634
      titzer authored 
      This reduces the storage per-Node storage from 7 words to 6 and per-edge
storage from 6 words to 4.
On average this is about 10%-15% space savings over the whole graph.

Remove the use of std::deque as the out-of-line storage for inputs.
Reduce size of Use links and use pointer arithmetic to find Node
from Use.

      [turbofan] Fix tail call optimization. · d21de2a4
      bmeurer authored 
      Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.

      [turbofan] Cleanup Graph and related classes. · e53845d4
      bmeurer authored 
      - Move NodeMarker to its own file, and introduce a non
  templatized base class.
- Cleanup the include hell.
- Sanitize the Node construction methods now that we
  got rid of that GenericNode/GenericGraph stuff.
- Protect against NodeId overflow in Graph.
- Various minor cleanups.
