Summary:
A plugin update allows infer to know when a function doesn't return
according to its attributes. This propagates this info all the way to
the attributes of each function, and then use this information in a new
pre-analysis that cuts the links to successor nodes of each `Call`
instruction to a function that does not return.
NOTE: The "no_return" `CallFlag.t` was dead code, following diffs deal
with that (by removing it).

Summary:
New clang in the plugin \o/
Changes that were needed:
- (minor) Some extra AST nodes
- defining a lambda and calling it in the same line (`[&x]() { x = 1; }()`) used to get translated as a call of the literal but now an intermediate variable gets created, which confuses uninit in one test. I added another test to showcase the limitation this is hitting: storing the lambda in a variable then calling it will not get caught by the checker.
The controller you requested could not be found.: facebook-clang-plugins

Summary: We get a lot of false positives for union types as union fields are treated as separate memory locations at the moment. For now we do not treat union fields as uninitialised.

Change the license of the source code from BSD + PATENTS to MIT.
Change `checkCopyright` to reflect the new license and learn some new file
types.

Summary: Use AccessExpressions instead of AccessPath in uninit analysis. This will allow us to distinguish between pointers and their dereferences.

Summary: In HIL, allow deref'ing a magic address like `0xdeadbeef` for debugging purposes. Previously, we would crash on code like this.
