We expect that the majority of malloc'd memory held by V8 is allocated in Zone objects. Introduce an Allocator class that is used by Zones to manage memory, and allows for querying the current usage.

MachineType is now a class with two enum fields: - MachineRepresentation - MachineSemantic Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably: - register allocator now uses just the representation. - Phi and Select nodes only refer to representations.

Verifies consistency of node inputs and uses: - node inputs should agree with the input count computed from the node's operator. - effect inputs should have effect outputs (or be a sentinel). - control inputs should have control outputs (or be a sentinel). - frame state inputs should be frame states (or be a sentinel). - if the node has control uses, it should produce control. - if the node has effect uses, it should produce effect. - if the node has frame state uses, it must be a frame state. I also removed some tests, either because they did not seem to be useful (scheduler) or they tested dead functionality (diamond effect phi).

This introduces the NodeProperties::ChangeOp helper which guards node operator changes so that additional checking can be done without any additional dependencies being pulled into the Node class. For now only the input count is checked, but additional checking might follow.

Along the way: - Thread isolate parameter explicitly through code that used to rely on getting it from the zone. - Canonicalize the parameter position of isolate and zone for affected code - Change Hydrogen New<> instruction templates to automatically pass isolate R=mstarzinger@chromium.org LOG=N Review URL: https://codereview.chromium.org/868883002 Cr-Commit-Position: refs/heads/master@{#26252}

Split lowering of Select nodes into a separate graph reducer and be more clever when lowering to diamonds, i.e. reuse diamonds that have the same condition and only add more phis to it.
