Split the interface into two functions: `enforce.*` returning the map by
value and `tryApply.*` returning an `std::optional`.
Improve non-positional single deduction function to better reflect
some corner cases (for example how a required `NoOrDead` register
argument is handled).
Enforce a position-based deduction corner case where it's impossible to
deduce whether the argument is passed in the GPR or the vector one -
now GPR takes precedence in those cases.
The `StackArgumentsType` field of `RawFunctionType` was the only
cross-reference between `model::Type`s that did not use
`model::QualifiedType` but a naked `TupleTreeReference`.
Switching it to `QualifiedType` make all cross-references across
`model::Type`s homogeneous.
Now all the generated `.cpp` include `Binary.h`. This ensures we don't
trigger the wrong concept due to forward declarations.
Also, this commit introduces a couple of `static_assert`s which should
enable us to early identification of similar problems.
