Summary: public Make it uniform with other function call translations. This is just reordering, no functional change intended

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.

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:
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

The clang location information is described in an incremental way: each location information is a delta with respect to the previous one in the AST. This is based on a the visit of the AST nodes which corresponds to the order in which the lines are printed with the standard clang AST dump:
clang -cc1 -ast-dump filename.c
This diff adds a preprocessing phase to the front-end so that location information is composed during a visit, and explicit location information is used instead.
In the case of include files, we report the last known location before including the file.
The current file for a function is the file where it is defined. So if a function is entirely defined in a .h file, then the location information will consistently be about the .h file. If instead a function is defined in the source file being analyzed, and some AST nodes come from macro expansion, line information will refer to the original file.
The front-end tests reveal that the location information was incorrect in a few dot files.
Test Plan: arc unit, after having fixed the wrong location in the existing .dot files
