- [x] Add three public fields to the "BoundVariable" service type: declarationTokenPos, visibleStartTokenPos, and visibleEndTokenPos. (naming suggestions welcome!)
- [x] Extend LocalVarDescriptors to hold the declaration token position (it already had the scope visibility boundaries).
- [x] Extend ContextScope to hold the declaration token position.
- [x] Add a unit test which verifies this works for local variables, function parameters, and closure captured variables.

For code objects, don't allocate symbol strings when printing the disassembly.
Don't try to make disassembling work with background compilation -- instead make sure that we don't allocate on the Dart heap while disassembling.
Add NoSafepointScope around disassemble functions to assert that no allocation happens.
Also, remove some dead code from object.cc.

The call sequence is very similar to a classic IC call, except the guarded class and the target are loaded indirectly from the constant pool instead of as immediates. In the monomorphic case, we call directly to the expected target with a class check in the callee. In the unlinked, polymorphic and megamorphic cases, we call a stub; these case are now call-through instead of call-and-return.
Every code, except stubs involved in switchable calls, includes the class check sequence at the beginning. So we now distinguish between a checked and an unchecked entry point. Generated code except the switchable call continues to use the unchecked entry point.
PC offsets are calculated relative to the beginning of the instruction stream, rather than either entry point.

not on the signature type hash anymore. This makes fingerprints insensitive to
implementation details of the type system. The signature type hash was included
because, in the early days, the token stream of a function started at the
opening brace and did not include tokens representing the signature.

- Use TokenDescriptor instead of intptr_t for all token positions.
- Use TokenDescriptor in raw_object instead of int32_t.
- TokenDescriptor is a POD with an int32_t (this shrinks the size of AST and IR nodes by 32-bits on 64-bit architectures).
There are some cleanups I plan on doing as a follow up CL:
- Replace TokenDescriptor::value() with TokenDescriptor::TokenPos()

- uses thread execution status transition to track when a thread is in a safepoint or needs to block for a safepoint
- introduces a monitor per Thread object
- uses a per thread safepoint handshake between the thread requesting a safepoint and the requested thread.
The ThreadRegistry class now contains only the thread list for an isolate and the functionality of scheduling a thread onto an Isolate and unscheduling it from teh isolate. We could fold this functionality into the Isolate class in a different CL.

Instead of collecting closures functions in each class object, maintain one list per isolate. This is a step towards getting rid of top-level classes.
I'd appreciate if John could take a look at the service isolate and coverage related change.
I'd appreciate if Ryan could take a look at the precompilation related change.
When compiling all of corelib, the list of closures in the isolate is about 600 entries long. If this linear list should become a bottleneck, I'll deal with it later. (Sadly, some code relies on the fact that a closure can be identified with a list index, so making it a hash table instead of an array does not work.)

Instead of one array for literal and identifier tokens for each TokenStream, share one array among all TokenStreams in an isolate.
The shared array and the token-to-index map is stored in the object store until the embedder is done loading. Then the map is thrown away (and the array remains shared, referred to by the TokenStreams).
When new files get loaded, a new shared array is created. For temporary scripts, e.g. when evaluating one-shot functions, the token arrays are not shared.
This eliminates many duplicate LiteralToken and identifier tokens. Looking at the core libraries:
Before: 30877 identifiers and 9618 literal tokens
After: 12899 identifiers and 6371 literal tokens

Address issue 21620, by sharing code to wait for concurrent sweeper to finish, and freeing the caller from this responsibility. The new public interface is Heap::Iterate*, and the old Heap::Visit* are made private, for GC use only.
(Eventually, we'll want to support iterating over the heap while concurrent GC runs, but that will have to wait until all header accesss is synchronized.)

Make the compact linked hash map, which is the default implementation for Map
(including map literals), a VM-internal class.
This makes it easy to have more efficient serialization of maps (although for
now, the implementation is straight-forward).
Refactor the compact hash class hierarchy to enable the VM-internal class and
the rest (also the Set classes) to share a maximal amount of code, by using
two different bases for implicit/explicit fields.
Remove existing proof-of-concept, C++-based internal VM-class.
