### Changes in `Microsoft.CodeAnalysis.Emit.EmitBaseline.CreateInitialBaseline` method

A new required parameter `Compilation` has been added. Existing overloads without this parameter no longer work and throw `NotSupportedException`.

### Changes in `Microsoft.CodeAnalysis.Emit.SemanticEdit` constructors
