Summary: Being forced to separately define `pp_element`/`pp_key` is uneccessary and makes it more cumbersome to create a set/map from an existing module that already defines `pp`.

Summary:
We've had some issues with names like `arr$` appearing in error reports.
Any identifier name that contains $ cannot have come from source code because it is not a legal Java identifier.
This change should stop these reports because Errdesc.ml refuses to use temporary var names in error reports.

Summary:
Utils contains definitions intended to be in the global namespace for
all of the infer code-base, as well as pretty-printing functions, and
assorted utility functions mostly for dealing with files and processes.
This diff changes the module opened into the global namespace to
IStd (Std conflict with extlib), and moves the pretty-printing
definitions from Utils to Pp.

Summary:
Functions related to source files were already namespaced by `source_file_` prefix. Make separate module for them.
In high level it replaces all `source_file_` with `SourceFile.` and then fixes all remaining compilation errors

Summary:
Remember which globals are static locals.
It's useful to distinguish those from global variables in objc and in the SIOF
checker. Previously in ObjC we would accomplish that by looking at the name of
the variable, but that wouldn't work reliably in C++. Keep the old method around for
now as the way we deal with static locals in ObjC needs some fixing.

Summary:
`DB.source_file_to_string` is very easy to misuse and it shouldn't even exist.
In preparation for that day, replace most of `source_file_to_string` with `source_file_pp`

Summary:
SIOF is only for interactions between objects of non-POD types. Previously the
checker was also reporting for POD types.

Summary:
- do a semantic analysis of each variable initializer to figure out if they need initialization
- add a flag to globals that is true when they are `constexpr`. In that case, no analysis is needed as the user + compile guarantee that it is a compile-time constant.

Checker for the Static Initialization Order Fiasco pattern:
https://isocpp.org/wiki/faq/ctors#static-init-order
1. Collect all globals (transitively) accessed in any given procedure.
2. Once the interprocedural analysis has finished, look at globals accessed in
initializers that do not belong to the current translation unit.

Summary:
Create dummy functions representing the initializers of global variables. This
is so we can implement checks in the backend that can look at the initializer
expressions of global variables. We try not to create these dummy functions
when the initializer is not present, although for some reason we sometimes end
up with empty initializers.
Also add source file info to global variables in the backend (Pvar.re).
