Alvise de Faveri a788a5ba62 Add helpers for inferring model types from the IR
1. Add a common helper to traverse ModelGEPs (`traverseModelGEP`)
2. Add a centralized way to deduce the model type of values that
   have strong model information attached to them (e.g. isolated
   functions and ModelGEPs)
3. Add a similar helper for deducing formal types of operands in known
   cases

Alvise de Faveri c2481aeb7b Support: Add deserializeFromLLVMString
Instead of having `paseQualifiedType` and `parseAndDeserialize`,
we now have a single function that is symmetric to
`serializeToLLVMString`.

Antonio Frighetto 4a045cce53 Introduce MakeModelCastPass
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.

Alvise de Faveri 73c743597b Pull out DepGraph and naming from ModelToHeader
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.
