The FastArray path for Array#groupBy and Array#groupByToMap does not recheck the input array's length each iteration. This is incorrect since the grouping callback can truncate the length, and we should deopt to the generic path when this happens.

Incremental finalization previously used to rescan roots to avoid any new work showing up in the atomic pause. With concurrent marking we should be way faster in finalizing, so that we can save ourselves this work. In particular, if we finalize in the same JS execution we would be doubling work as the atomic pause anyways needs to rescan all roots.

When the heap is gracefully terminated, all the destructors are called. CrossThreadPersistents must clear the back references (references from CrossThreadPersistentRegion) so that further GCs on other threads will not access freed CTPs. To force destruction with young-gen enabled, the CL unmarks the heap on termination.

This includes two fixes: 1. For dynamic tiering, the budget must always be reduced when jumping backwards, otherwise we might never trigger tier up, which makes the loop non-interruptible (because the tier-up check replaces the stack check). 2. The d8 worker implementation also needs to terminate the isolate via an interrupt, in addition to scheduling a task, because the worker might never return to the event queue. This CL also fixes one of the failure modes of the inspector fuzzer (see https://crbug.com/1180018).

Remove cctest's ability to run multiple tests (which has long been deprecated and mostly broken). We can then make platform & V8 initialisation be part of running the test's Run method. In particular, this allows us to inject custom logic into the platform initialisation, like setting up a platform wrapper. Add a TEST_WITH_PLATFORM which exercises this by registering a platform factory on the test, and wrapping the default platform using this factory. This allows these tests to guarantee that the lifetime of the platform is longer than the lifetime of the isolate. As a result of this, we can also remove the complexity around draining platform state in the TestPlatform (since it will now have a longer lifetime than the Isolate using it), and as a drive-by clean up the TestPlaform to use a CcTest-global "default platform" instead of trying to scope over the "current" platform. As another drive-by, change the linked-list of CcTests and the linear search through it into an std::map of tests.

Port the eager deopt handling in the use marker and register allocator to do the same thing with lazy deopts. This requires moving the lazy deopt info to be a pseudo-input before the node, same as eager deopt info, so that the regalloc can read it without needing the Node's opcode. For now, this means that a node cannot both eager- and lazy-deopt; if we need this in the future we can rethink it.
