This change adds support for allowing for imports of unsupported
platform-specific libraries when the
`--include-unsupported-platform-library-stubs` flag is provided to the
CFE.
This flag sets the `includeUnsupportedPlatformLibraryStubs` property in
`TargetFlags`, which `Target`s can use to conditionally return different
`DartLibrarySupport` objects with different supported/unsupported
library sets.
A `checkForUnsupportedDartColonImports` function has been added to
`Target` that uses the value of `dartLibrarySupport` to determine if
there's any unsupported library imports. This function is called after
the various transformation operations provided by the `Target`
implementation, meaning the import of an unsupported library specified
in `dartLibrarySupport` will now result in a compilation error (this
includes `dart:mirrors` imports for VM targets when mirrors are
disabled, which was previously handled by the VM itself).

This adds an internal wrapper expression for redirecting factory invocations. This holds a reference to the original redirecting factory constructor along with the resulting invocation of the generative or factory constructor. The node is removed during constant evaluation and only available to backends through the pre-modular transformations.

For expression evaluation we want to be "more than dart" in that if for
instance we can see (in the debugger) that a List contains `B`s (even
if it's typed as containing `A`s) we'd like to be able to access things
on `B` (without manually having to cast to either `B` or `dynamic`).
Furthermore - when we in the debugger can see that it's a `B`, and that
`B` has, say, a field `_privateField` or a method `_privateMethod` we'd
like to be able to access that even if `B` is in another library.
This CL - for expression evaluation - makes dynamic accesses and calls
where we would normally issue a "missing getter" (etc) error, and tries
to create a `Name` so private access is possible.

This adds the library reference of private names of other libraries in
the ast-to-text of member declarations. This prepares for a fix of the
library used for private constructor tear offs.

This adds the flag isErroneouslyInitialized to the VariableDeclaration
AST node in Kernel. The flag is set to true whenever it is concluded
during compilation that the initializer contains errors is erroneous
for the parameter in any other way, for exaple, due to a type mismatch.

This adds a flag to the member descriptors that allow us to skip these when building the name space for extensions and extension types from dill.
The late lowering of fields in dart2js is fixed to support lookup from dill.

ExtensionTypeMemberDescriptor.memberReference and
ExtensionMemberDescriptor.memberReference are now nullable.
TFA-based tree shaker can now set them to null when extension type
member is not used and removed but corresponding lowered tear-off is
still used and retained.
Front-end never sets them to null and requires non-null memberReferences
when consuming kernel.
