This will allow it to be used by front_end unit tests.
Also plumb through the "ignoreSdk" boolean, since we will need to use
it when invoking the naive type checker from front_end unit tests.

Previously lazy loading was done in Procedure by lazy loading functionNode,
now lazy loading is done (only through Procedure) in the functionNode by
lazy loading the body.

Before: mixin application classes could not have methods of their
own.
After: type inference will sometimes insert forwarding stubs in mixin
application classes. In the mixin elimination transformation, these
forwarding stubs are replaced with the methods of the mixin class if
they have the same name, but the parameter flags from the forwarding
stub are retained. The other forwarding stubs are left as methods of
the class.

Change abefb7b432 introduced a typing issue
instead of fixing it: _SyncIterator<T>._current was actually used to return
either a value of type T (for yield) or value of type Iterable<T> (for yield*)
from the move callback.
This change refactors implementation of _SyncIterator in such a way that
_current is only used to return value for yield and a separate field
_yieldEachIterable is used to return Iterable<T> for yield*.

Since 'DartType's overload equality with a structural comparison, we cannot
store metadata for them in a 'Map', as is done for 'TreeNode's. Since there is
no use-case yet for storing metadata on types, we remove this ability and the
restrict the metadata test.

This flag indicates when a procedure's return type makes contravariant
use of a class type parameter. The front end will have to insert "as"
checks at any call sites that refer to such a procedure as their
interface target. Placing the flag on the procedure will allow the
front end to determine whether the check is needed once, at the same
time as it's determining the need for covariant parameter checks,
rather than when compiling individual call sites.
Once this lands I will follow up with CLs that cause the front end to
set the flag appropriately, and to generate the necessary "as" checks.

This will be necessary when we try to integrate type inference with
the creation of forwarding nodes, because getter types can be inferred
from inherited setters and vice versa.
We accomplish this by producing two separate lists (getters and
setters), then merging them together. This results in a list where
correspondingly-named getters and setters are grouped together, with
getters appearing before setters.

Devirtualization optimization now adds metadata to kernel AST instead
of transforming nodes to Direct* ones. The direct call metadata
provides information about checking receiver for null, while
Direct* kernel nodes do not support null checking.
VM's kernel binary loader is extended to extract arbitrary metadata
from kernel binaries and keep it for flow graph builder.
Kernel flow graph builder is extended to take direct call metadata
into account and generate CheckNull/StaticCall instructions
for devirtualized PropertyGet, PropertySet and MethodInvocation nodes.
