Summary:
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:
This diff removes the unused support for reporting props, which enables
refactoring so that the 'base' directory has no dependencies, and the
'IR' directory depends only on 'base'.

Summary:
This is needed for later: InferClang will no longer be started once for each
source file to be analysed. Instead, it will be called to analyse several files
at once, and will analyse them one by one. Thus, `clang_lang` and `source_file`
are moved to `cFrontend_config` as references.
The biggest change this entailed was the new logging infrastructure, which was
depending on `Config.source_file`. This diff moves the logic entirely to
`Logging`, and changes the API so that executables wishing to log into files
have to set it up using `Logging.set_log_file_identifier`. This can be called
several times during the execution, allowing to dynamically change the log file
(eg, when analysing several source files one by one!).

Summary:
In order to have only InferJava depend on JBasics, do not use
JBasics.java_lang_object in the IR or backend. Note that this implies
that the Java frontend should ideally translate JBasics.java_lang_object
to Typename.Java.java_lang_Object.

Summary:
Change Sil.Call instruction to have only a single optional return
identifier, insted of a list. Essentially none of the code handled
multiple return identifiers. Also, add the type of the return
identitifier to Call instructions.

Summary:
Refactor Sil.struct_typ and associated operations into a separate
StructTyp module. This is possible now that Typ.Tstruct only carries a
type name instead of the definition directly, and is helpful to simplify
module dependencies.

It is no longer necessary to keep the name of a struct within the

Summary:
The global reference `DB.current_source` is used internally in the module DB, by all the front-ends, and directly and indirectly by the back-end, including saving and restoring the state in case of on-demand procedure calls. In particular, it is heavily used in printing functions.
This diff cleans up the flow of information about what the current file is, making it explicit, and removes the reference.

Summary:
This diff removes the redundancy in the representation of types where
struct types could be represented either directly using Tstruct or
indirectly using Tvar to refer to the type environment. A consequence
is that it is much harder to construct large type values.
