Edited Unassigned: Performance: InitializeDatabase regressed by changeset 1911dc7cef21 [1194]

[Changeset 1911dc7cef21db6e630b9258d53584a326438cc8](https://entityframework.codeplex.com/SourceControl/changeset/1911dc7cef21db6e630b9258d53584a326438cc8) introduces a performance regression to the database creation process of up to 22% (in very large models) when compared to previous versions of this same code.

The culprit of this performance regression is the new call to DbContextExtension.GetDynamicUpdateModel as part of the DbMigrator ctor.
