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?

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.

Summary:
Infer's [`install-sh`](https://github.com/facebook/infer/blob/master/install-sh) knows to "correctly" read from the `TMPDIR` environment variable:
- https://github.com/facebook/infer/blob/master/install-sh#L327
However, this was not supported by `clang/setup.sh`.
I haven't overlooked the existence of `CLANG_TMP_DIR`, but I had (initially) set `TMPDIR` hoping Infer's build system would honour it (it didn't) -- consequently, I thought it would be useful for future users if Infer honoured this.

- The SDK path is different for Objective C when command line tools for Xcode are installed without Xcode itself.
- Related issue https://github.com/facebook/infer/issues/1002.
I still have a problem with the mentioned issue. I think that it is possible that the SDK paths differs for Objective C on Mac OS when I have installed just command line tools for Xcode without Xcode itself. This change solves the issue for me. Is it a good solution? Could it be possibly added to Infer? Or is there any better way?

To distinguish non-ARC-/ARC-compiled:
* extended `translation_unit_decl_info` to have a boolean field `is_objc_arc_on`
* then copied it to `ProcAttributes.t` for each procedures.

Summary:
## Issue
There are a number of times when users building `facebook-clang-plugins` hit memory limitations, typically due to the OOM killer and when linking.
In https://github.com/facebook/facebook-clang-plugins/pull/21, I implemented support for building `facebook-clang-plugins` using both Ninja and to only use one process when linking.
## Resolution
This PR exposes the optional flags added in https://github.com/facebook/facebook-clang-plugins/pull/21 to `build-infer.sh`, such that you can build `facebook-clang-plugins` with either just `ninja` or `ninja` + only one process for linking.
As part of this, it updates the `facebook-clang-plugins` submodule.

Summary:
This translates the construct `ObjCBridgedCastExpr` when the cast_kind is `OBC_BridgeTransfer`, or in syntax, the cast (`__bridge_transfer`).
This cast means that the object is passed from manual memory management to ARC, so one doesn't need to call `release` manually. It is important to model this to avoid false positives.
It translates it as a builtin that we then model in Pulse, the same way we modelled `CFBridgingRelease` which does the same thing.
The name of the builtin is `__free_cf` which is not ideal but I left it like that for compatibility with biabduction. We can change it once we remove this check from biabduction.
