The `Base.getproperty` method for `PartialStruct` has a type assert to ensure type stable access of the field `undef`. However Compiler.jl has `Compiler.getproperty === Core.getfield`. Introduce a getter for this field of `PartialStruct` into Compiler.jl and use it. I guess this should improve compiler performance, and it should help avoid spurious invalidation.
