Looking up a name x in the library scope or in a prefix can also return
the setter name x=. There were several situations that were not handled
right.
- a getter x and a setter x= should not result in a duplicate name
error (and thus a resolution error at runtime).
- when looking for an untangled name x but a setter x= is found first,
keep looking for x.

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)

- 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.

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.

- Rework token position address space.
- Use ClassifyingTokenPositions::kMethodExtractor for the token position of a method extractor.
- Plumb token positions through all of Ast Transformer.
- Plumb token positions for temporary expressions, etc in Flow Graph Builder.
- Add token positions for parts of the await machinery.
- Move ClassifyingTokenPositions into token.h.
- Remove default token position of Scanner::kNoSourcePos for many IR instructions.
- A couple of unit tests.
- Use synthetic token positions for synthetic AstNodes.
- Fix SLEB128 encoding / decoding + test
- s/Scanner::kNoSourcePos/Token::kNoSourcePos.
- Remove >= 0 and < 0 checks against token positions and use helpers instead.

Also take the opportunity to add the ability to report an error after a given token position. This way, the missing semicolon gets reported where it should: at the end of the line rather than the first token on the following line, when the error is actually detected.

- Give AwaitMarkerNode a token position.
- Make it possible to provide a token position for SaveContext, RestoreContext, StoreContext, and CurrentContext.
- Pass in a token position to internally generated StoreLocal and LoadLocal instructions for try-catch-finally.
- Introduce a Context ClassifyingTokenPosition to be used when we can't attribute a context related instruction to a source position.

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?

Arguably method extractors, invoke-field dispatchers and noSuchMethod dispatchers should also have their token position as kNoSourcePos instead of 0, but this would complicate how parser initializes its token iterator, so I'm leaving them as is.

There were two exception handlers with the same index added to the code so that only the one added
last was executed. In case of an exception that means that a re-throw may be omitted, causing invalid
control flow.
Also, add assertion to ensure unique try-index for exception handlers.

Evaluate and canonicalize the parameters to the built-in function
identical(a,b) if they are strings. This guarantees that
identical(“ab”, “a”+”b”) evaluates to true.
Note: when the parser parses “a”+”b”, it doesn’t know whether the
expression will be used in a context that may require a
constant value. The canonicalization is thus deferred until it is
known that it is required.

When --move_super is true (the default value), the super constructor call
is moved to the end of the initializer list. In that case, the phase parameter
is not necessary. This change eliminates the check of the phase parameter in the constructor code, but does not yet eliminate the phase parameter.

Introduce --warn_super flag to print a warning when a super call is found that is not at the end of the initializer list.
Mark failing tests as Fail, OK.
In a later step, we can eliminate the implicit 'phase' parameter in constructors.
