Regis Crelier e66d65f7b9 Change function source fingerprint calculation to rely on tokens exclusively and
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.

John McCutchan d77d376124 Replace intptr_t with TokenDescriptor
- 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()

Siva Annamalai e72c1fb47d Implement safepointing of threads :
- 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.

Matthias Hausner 648e52baa8 Collect closure functions in isolate
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.)

Matthias Hausner 59dce43dfe Shared token objects
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

This makes it easy to have more efficient serialization of maps (although for

the rest (also the Set classes) to share a maximal amount of code, by using
two different bases for implicit/explicit fields.
