Hi Momchil,

I debated on this change, because it is undoing what I did previously and it is based on review feedback.

The implementation is fine and correct. It is a matter of principles.

I am going to approve because:
1) If we revert this patch in the future nothing should break as it is a NFC*(At least that is my understanding, with the exception of the change in file ASTContext.cpp)
2) There are a list of patches approved that depend on this.


At least that is how I am approaching this implementation of mfp8.
