A pass that strips the casts off from some instructions, including
`ModelGEP`s, general function calls, return and store ones, and
embeds the cast into new dedicated `ModelCast` function calls.
Change company name to "rev.ng Labs Srl" in all license headers
to reflect changed company name and legal status
Add missing license headers to files that didn't have one
Separate `ModelToHeader.cpp` into 3 different files:
1. DependencyGraph, used to calculate the precedence between
type declarations
2. ModelTypeNames, that holds all the naming logic, whose
primitives are accessible from other modules through a
public header
3. ModelToHeader, that now contains only the logic to print
out declarations and definitions
Also add a compilation test for the headers generated by this pass.
