Model classes are now described by a YAML document, which is used to
generate C++ headers containing classes and all the boilerplate
required for YAML serialization/deserialization, usage in
SortedVectors, etc. See the README in include/revng/Model for more
info.
Before this commit `is_specialization<const X<T>, X>` was not
specialized, so that `const X<T>` did not count as a specialization of
`X`. This resulted in bad selection of template specialization based on
concepts that were using `is_specialization_v`, such as
`IsUpcastablePointer`.
This commit fixes the problem, so that now the concept
`IsUpcastablePointer` is true for `const UpcastablePointer<T>` as well.
This also enabled to remove some workarounds for the `IsMutableSet` and
`IsSortedVector` concepts, and treat them uniformly with other concepts
that were using `is_specialization_v`.
This commit fixes a couple of bugs preventing SortedVector and
MutableSet from being serialized.
Also, it introduces minimal testing for serialization.
These data structures are substitutes for a `std::map<Key, Value>` where
`Key` is embedded in `Value`. Their main goal is to be serializable in a
YAML sequence while preserving the order enforced by the key.
`MutableSet` is implemented using a map.
`SortedVector` is implemented using a sorted vector.
