Summary: public
Dictionary literals are normally implemented using
`+dictionaryWithObjects:forKeys:count:` but were modeled as
`+dictionaryWithObjectsAndKeys:`
In particular, `@{@"aaa": nil}` would trigger a sentinel error instead of an NPE.
This models dictionary literals as a special infer builtin that the backend
interprets so as to give NPEs when passed nil objects or keys.

Summary: @public
This removes the old way of finding variable declarations to create sil variables and replaces it with
a a new way based on the map from pointers to declarations.
Basically, every variable dereference contains a pointer to the variable declaration, with that we can
build the corresponding sil variable.

Summary:
This is the second of 3 stack diffs to deal with replacing the parser of types.
This diff is about changes to translate record types, as well as class types and enum
types. For class types and enum types we store the declaration pointer in the map of
types to find the type easier later.
For record declarations, we change the way we build record names.
Moreover, we don't translate typedefs anymore, because when we have a pointer to a typedef,
we can find the actual type it points to.
Summary:
each procedure has a different scope, so we can restart the fresh name generator and have more stable instructions in the cfg, that don't change when other procedures are changed
Summary:
The methods in objc can have the same name in the same class, but one be instance and the other class,
so that we need to take the instance flag into account when defining unique names for ObjC methods.
Summary:
This adds a sentinel check every time a function carrying a sentinel attribute
is called, regardless of whether we have a definition for that function or not.
