Introduce class TypeRef in the VM to fully support recursive types.

Fix issues 15244, 15148, 14869, 14000, and 13688 (was closed, but fragile).
Note that the current solution is not final as it may not be correct in more
complex cases not yet covered by language tests.
The final solution will require a 'trail' instead of a simple mark bit to
prevent operations involving recursive types to diverge.

Fixes a couple problems with GC of unoptimized code.
...
1. Instead of making a pass before the Marking phase,
this change does not visit code pointers in functions
during marking. Then after marking, if the code has
still not been marked, code pointers in functions
are nulled out.
2. Since code pointers in functions may be nulled out,
functions are no longer used as proxies for code in
deoptimization info.

The AST for static getters differs between parsing the first time, and
subsequent parsings. This leads to a mismatch in deoptimization-ids
between the optimized and the unoptimized code.
This CL avoids creating different ASTs for the same static getters. To allow
better inlining of these getters, the initialization expression is wrapped in a
hidden static initializer-function. As a result the size of such getters is
constant and does not depend on the initializer expression.

Faster invocation of fields as methods.
...
Until now there was a large discrepancy between
x.f() and
(x.f)()
This CL makes x.f() as fast as (x.f)() by automatically
generating a intermediate dispatcher function that loads
the field and invokes the result as a closure.
The approach resembles the one taken for fast noSuchMethod
invocation and reuses the same per-class cache
of dispatcher functions.
It also fixes a bug in the debugger so that VM-generated
implicit dispatcher functions (like for noSuchMethod, or
field-as-method invocation) don't show up the debuggers
stack trace.

Support fast noSuchMethod dispatch for any number of arguments.
...
Until now, the fast dispatch was only available with getters and
zero argument methods.
This CL generalizes the approach to any number of arguments. The
dispatcher functions that are auto-generated by the compiler
are not attached to the class anymore. Instead the dispatcher
is only stored in the IC data of each call site. Each class
contains a cache of dispatcher function that map
(name, arguments descriptor) => dispatcher.
This also fixes a bug where the VM report a wrong error message
when throwing a NoSuchMethodError.

Optimizing noSuchMethod invocation with no arguments.
...
On each call that triggers a noSuchMethod invocation we
attach a custom dispatch function that allocates the
invocation object and invokes noSuchMethod. This dispatcher
is compiled and optimized like a normal Dart function.
Similar to method-extractors, these implicit dispatchers
do not show up as normal functions.
As a first step this CL only handles invocations of getters
and methods with no like o.foo or o.foo(). This CL gives
a >25x speedup of such noSuchMethod invocations. Calls with
multiple arguments still go through the slow path.

Make ImmutableArray a sub class of AllStatic.
...
This enables Array to be a FINAL_HEAP_OBJECT and the operators
'=' and '^=' would be a simpler implementation which does not
require a call to initializeHandle().

Add deoptimization history to optimized functions.
...
Each function that is optimized or inlined into an optimized
functions keeps an array of deoptimization ids.
This history is used to avoid repeated deoptimization caused by
speculative hoisting of check instructions.

Delay Class parsing until the class is actually used.

Prior to this change the initial heap sizes were as follows:
ia32:
Size of isolate snapshot = 1230921
New space (0k of 32768k) Old space (1446k of 1604k)
X64:
Size of isolate snapshot = 1223943
New space (0k of 32768k) Old space (2630k of 2692k)
After this change the initial heap sizes are as follows:
ia32:
Size of isolate snapshot = 686443
New space (0k of 32768k) Old space (677k of 836k)
X64:
Size of isolate snapshot = 684731
New space (0k of 32768k) Old space (1220k of 1412k)

- Remember the fact that an object has been added to the
...
store buffer by a bit in the header.
- This bit can be used to filter out redundant additions
into the store buffer making the dedup sets not needed.
- Remove the need for a HashSet when remembering old to
new references.

except during snapshotting.
- Move the kWatchBit into the available space as its

Fast copy between TypedData and ExternalTypedData
...
Until now, copying data from TypedData to TypedData and from ExternalTypedData
to ExternalTypedData was fast. But copying between TypedData and
ExternalTypedData was not handled in a fast way.
