- Remove `CreateInterProceduralTypes` and `CreateIntraProceduralTypes`
from the StepManager and put them in a separate
`DLATypeSystemLLVMBuilder` object that is in charge of initializing
the DLATypeSystem graph.
- Remove `MakeLayouts` from the StepManager and split into two free
functions: `makeLayouts` and `makeLayoutMap()`
- Remove all LLVM-related stuff (Module, LayoutTypePtrs and mappings
between these and DLATypeSystemNodes) from DLATypeSystem
- Add an IntEqClasses member to DLATypeSystem, to use to map between
LayoutTypePtrs and Layouts
- Add a TSDebugPrinter object inside the DLATypeSystem, which by default
prints only IDs
- Define an LLVMTSDebugPrinter inside DLATypeSystemBuilder which
overrides the default printer's behavior, printing LLVM-related info.
- Add the possibility to dump into a .csv file the bindings between
Nodes in the TypeSystem and `llvm::Value`s
