Move optimizations for precompilation into separate file.
Remove precompilation-specific code from flow_graph_optimizer.cc.
Add precompilation-flags: They are const in the precompiled runtime. Started moving flags to use the new flag-definition macros.
Add libdart_lib_precompiled target.
Define PRECOMPILED_RUNTIME_MACRO in more places (dart_precompiled_runtime)

Async generators should only react to a cancellation when they
yield a value. Otherwise, the cancellation is ignored.
The example in dartbug.com/23436 should therefore never terminate,
because the generator function contains no yield statement.
This CL fixes bug 23436 by implementing the expected behavior, i.e.
not terminating the generator. If a yield statement is added to the
generator, the finally clause is executed once only, as expected.

- 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.

- Cleanups to the embedder's Dart sources for the service isolate. This lets us stop keeping a local copy in the mojo and flutter trees.
- Let the VM know Observatory's server address.

They were used as the class of closure instances and as the type class of
function types.
All closure instances now have class _Closure and function types are represented
by a new class FunctionType extending AbstractType.
Fix issue 24567 and add regression test.

Super initializer calls get implicitly moved to the end of the initializer list, so we don't need the two-phase constructor protocol anymore.
Ryan, can you please look at the mirror changes and check wether I've missed something?

Three types of fixes:
1. Remove redundant const_cast
2. Remove const_cast by adding const when appropiate.
3. Remove const_cast by removing const (e.g. places where we call free with it)
For now I only fixed places where the fix is local enough - i.e. does not require
changed a large amount of code.

Each script has an associated top-level class in which the top-level functions and fields are stored, and the reference to the script. All other fields in the TL class are unused. There are 380 TL classes in corelib alone; eliminating them saves space.
This CL eliminates all TL classes but one per library. All TL functions and fields in the library are stored in that TL class. Because scripts are not stored directly in functions and fields, but are accessible via their owner class, the owner of TL entities are now PatchClasses, rather than classes.
