The enum `ProcedureStubKind` together with the flag `isSynthetic`
replaces the flags `isForwardingStub`, `isForwardingSemiStub`,
`isNoSuchMethodForwarder` and `isMemberSignature`.
The semantics of the existing properties on `Procedure` is unchanged.
The new MixinStub and MixinSuperStub stub kinds are not used yet and
the stub target for NoSuchMethodForwarder is not set yet.

This is in preparation to migrate package:kernel to null safety.
For the visitor interfaces to support non-nullable return types, the
implementations must avoid using `null` as return value in its base case.

Simple calls to `List.generate` are expanded into a list allocation
and a loop. This generates better code for several reasons:
- There is no overhead for the function argument (closure allocation,
closure type, closure class)
- Global type inference is more precise since each List.generate list
is tracked separately, and the assignments in the loop give better
inference to the collection's element type.
To get precise element type inference, there are two new JSArray
constructors. Global type inference starts with the element type being
bottom for these elements, avoiding spurious nulls in the inferred
type.

This CL adds predefined constructors to LateInitializationErrorImpl that
only take the name of the late field/variable as argument. This can reduce
the size of the generated code for ddc/dart2js size because the long

ClassLevel and Class.level have been unused for (at least) years.
This CL removes them.
Library.flags furthermore had the first bit unused after the 'external'
flag was removed (last year I think).
This CL shifts it down so the actual flags doesn't start at bit 1.

Most of the time one already knows at the call site if it's a Field,
a Procedure etc --- so use that instead.
For now I'll leave the corresponding getters that are basically
documented as "don't use" ("[...] for convenience, not efficiency.
Consider manually iterating the members [...]").

This adds a mechanism similar to that used in async functions where
exceptions are caught in the synthetic code and passed into the
generated body to be rethrow'n.
This ensures the exception is throw'n from the same place as the
original yield*, as per the spec.

If they don't, silently do not initialize from the file.
* When serializing and deserializing, assert that the individual

* When appending dill libraries in the CFE, assert that they match

* Remove NonNullableByDefaultCompiledMode.Disabled -- it's not a thing
