The redirecting factory List:: is currently removed and replaced with the actual target at the callsites during construction of kernel, but referencing the actual target here would make the transformation platform specific.

"Covariance checks" are checks on certain parameters, necessary due to
the unsafe covariant subtyping rule for interface types.
The new pass generates a checked entry point for each method with
covariance checks. This entry point checks the parameters whose type
cannot be trusted, and then calls the actual method implementation.
Every typed call is then redirected to the checked entry point if the
interface taget declares any parameters with unsafe types, unless the
receiver is 'this'.
Dynamic calls and covariant overrides are not addressed by this CL,
these are still unchecked.

This is the result of:
- taking the diff of the branch closure_conversion to master in the kernel
repository
- updating the file paths
- applying the diff to the Dart SDK
- fixing conflicts between the changes to pkg/kernel in the Dart SDK and the master branch in the kernel repository
