Summary: public This diff changes the way we treat enums in Infer.
1. The semantics of the translation is now correct, it was a bit incorrect before.
2. We don't add the enum types to the tenv anymore, which saves a lot of disk space
and avoids errors in the backend dealing with the enum type.

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.

Get newest goodness from facebook-clang-plugins
that allows us to change type of type_ptr during deserialization
We are modifying clang_ast_types.ml that fcp/clang-ocaml expects to
exist - we provide our own implementations of:
t_ptr, pointer_to_type_ptr, type_ptr_to_pointer

qual_type was the same as type_ptr, so it was removed.
This commit makes it compatible with facebook-clang-plugins
Commands ran:
codemod --extensions ml,mli 'qual_type' 'type_ptr'

If there is any other popular name for qual_type, let me know

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:
Move proc_attributes to a separate module.
Field err_log, in common between proc desc and summary, can now be moved to ProcAttributes without creating cycles of dependencies.
Summary:
There's a lot of overlap between the representation of a proc desc and a spec summary. This diff moves all the data in common to the single record proc_attributes defined in Sil.
This gives a unified way of accessing most of the data carried by a procedure, whether it is contained in a proc desc or a spec. Also, it ensures that there is a single flow of information from proc desc to spec in the back-end, making sure that the information represented stays consistent.

Summary:
This makes infer C frontend compatible
with new scheme for naming which has:
1. plain name (like 'fun')
2. qualified name (reversed list like ['fun', 'class', 'top_class', 'namespace'])
Summary:
@public
This adds basic support for function attributes in Sil, and for translating
attributes from the clang frontend to these new Sil attributes. For now only
the sentinel attribute is translated.
Note that attributes normally have parameters, but they are currently missing
from the clang plugin.
Test Plan:
Add
(match Sil.get_sentinel_func_attribute_value (Cfg.Procdesc.get_attributes callee_pdesc).Sil.func_attributes with
| Some _ -> L.out "found sentinel attribute!\n"
| _ -> ());
between lines 947 and 948 of symbExec.ml, then analyze a file containing:
int add_all_ints(int a, ...) __attribute__ ((sentinel));
int foo(void) { return add_all_ints(1, 2, 3, (void *)0); }
then `grep 'found sentinel' infer-out/log/analyzer_out`
-> the sentinel attribute is correctly passed from the frontend to the backend.
