Implement AtomicExpr translation ( #1434 )
...
Summary:
Implements the translation of most clang atomic builtins to SIL, including those used in `stdatomic.h`. It does not attempt to model the atomicity of the operations, since I don't know of any way Infer can represent that. I didn't bother implementing the rarely used min/max builtins, so they're left as `BuiltinDecl` calls.
This is my first major OCaml project, so any feedback is appreciated!
Also, CONTRIBUTING.md says to update the [facebook-clang-plugins](https://github.com/facebook/facebook-clang-plugins ) submodule, but it doesn't seem to be a submodule anymore, and the code has diverged from that repo. Should I still make a PR over there?

Fix clang plugin compile error in FileUtils.cpp ( #1437 )
...
Summary:
I ran into this error while compiling:
```
[*ERROR**][48253] FileUtils.cpp: In function ‘std::string FileUtils::makeAbsolutePath(const string&, std::string)’:
[*ERROR**][48253] FileUtils.cpp:44:57: error: invalid initialization of reference of type ‘const string&’ {aka ‘const std::__cxx11::basic_string<char>&’} from expression of type ‘llvm::StringRef’
[*ERROR**][48253] 44 | const std::string &element(llvm::sys::path::filename(path));
[*ERROR**][48253] | ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~
```
The path element in FileUtils.cpp was attempted to be initialised from an `llvm::StringRef` directly, which doesn't appear to be a thing that is implemented anywhere. This PR simply dereferences the `StringRef` to an `std::string` with `str()`, which makes the compile error go away.
The complete compile error output is as follows:
```

[siof] detect constexpr for all procedures
...
Summary:
Previously we were only taking constexpr into account on constructors.
Add this info to ProcAttributes.t instead by exporting it from the
plugin for all functions.
This allows SIOF to take constexpr into account in more cases as it's not
always good at capturing which functions *can* be constexpr-evaluated,
which caused false positives.
Delete now-useless is_constexpr in constructor types. This generated the
changes in frontend tests.
Some minor renamings of variants of is_const_expr -> is_constexpr.

Update Infer to LLVM (clang) 11.1.0.
Infer/clang now uses the LLVM 'monorepo' release, simplifying the download script.
Some changes done to how/when ASTExporter mangles names, this to avoid the
