The uninitialized case in the StoreIC doesn't use any feedback.

This switches from copying entire runtime stubs into each module to only having small jump table slots in each module that act as a trampoline to the actual embedded builtin representing the runtime stub.

We'll let the bytecode compiler and optimizing compilers deal with dead code, rather than the ast visitors. The problem is that the visitors previously disagreed upon what was dead. That's bad if necessary visitors omit parts of the code that the bytecode generator will actually visit. I did consider removing the AST nodes immediately in the parser, but that adds overhead and actually broke code coverage. Since dead code shouldn't be shipped to the browser anyway (and we can still omit it later in the bytecode generator), I opted for keeping the nodes instead.

Each page has a `live_byte_count_` field in its header and it is always accessed with atomic operations. However, apart from one corner case, this field is only accessed by the main thread so let's remove the atomicity by default. To summarise, this changes the MarkingState accessors in the following way: - IncrementalMarkingState: Accesses of live_byte_count_ are now non-atomic. Concurrent marking uses local maps of live bytes per page so we have exclusive access to the field when using this. - MajorAtomicMarkingState: This accessor does not guarantee exclusive access to live_byte_count_ so we need to keep the access atomic. This is used by the scavenger when migrating an object that was marked black, since marking an object black will implicitly increment the live_byte_count_. Additionally, the live_bytes() and SetLiveBytes() accessor methods were not used so remove them. - MajorNonAtomicMarkingState: Accesses of live_byte_count_ are not actually non-atomic. - MinorNonAtomicMarkingState: The `young_generation_live_byte_count_` field is atomic so we can set the memory order manual to relax accesses.

Prior to this change, all samplers attached to an isolate received samples when other samplers sent SIGPROF to the VM thread. This change alters the behaviour of different CpuProfiler instances on the same isolate to be in line with the Windows / Fuchsia behaviour.
