Summary:
Races on volatile fields are less concerning than races on non-volatile fields because at least the read/write won't result in garbage.
For now, let's de-prioritize these writes by ignoring them.

Summary:
Similar to marking classes ThreadConfined, we want to support marking fields as well.
The intended semantics are: don't warn on writes to the marked field outside of syncrhonization, but continue to warn on accesses to subfields.

SuppressWarnings annotations are hardly used and add considerable

Summary:
Utils contains definitions intended to be in the global namespace for
all of the infer code-base, as well as pretty-printing functions, and
assorted utility functions mostly for dealing with files and processes.
This diff changes the module opened into the global namespace to
IStd (Std conflict with extlib), and moves the pretty-printing
definitions from Utils to Pp.

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

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.

Summary:
Now that array types record only static - and therefore constant -
lengths, Sil typ and exp no longer need to be mutually recursive.
This diff:
- splits the recursion in the type definitions of typ and exp,
- splits the recursion in the comparison and pretty-printing
functions,
- and then refactors typ into a separate module.

Summary:
If we see a read of a field f annotated with GuardedBy("mLock"), we spring into action.
What we do is look for some hpred `A.mLock |-> B` and return `B` as the "guarded-by object".
Once we have models for montitorenter/exit in place, `B.__inferIsLocked = true` will mean "lock held", and `B.__inferIsLocked = false` will mean "lock not held".

Eliminate the use of the -open Utils command line option passed to the compiler in favor of `open! Utils` in each source file. While slightly convenient, this option causes more headaches than it is worth with other tools e.g. merlin.

Summary:This pull request adds the SuppressViewNullability annotation.
The reasoning behind this is that in libraries, one cannot use Butterknife for view binding, which forces you to do it manually. Basically, this makes a new annotation that infer treats the same way as Bind/InjectView

Summary:public
Instead of using the collection of suppress warnings annotations to filter out the errors while generating the error reports, we just add this SuppressWarnings at translation time, like any other annotations, and the reporting functions in the Reporting module will just skip the errors when the method is annotated with SuppressWarnings.
This allows us to have a suppress warnings mechanism that is independant from the integration with the build system.

I have seen enough comments in this space by people during code review to switch on the analyses the compiler can already do. This diff is an automated renaming of unused identifiers to _, with a few additional changes made when reading the diff of the results for things that stood out as particularly strange. This base-lines all of the existing warnings. I'm not sure this is a good idea, since it might be better for those familiar with each part of the code to look at these warnings and use them as pointers to suspicious code.

Add to the code to detect violation of the `NoAllocation` annotation. This diff adds the code to detect such issue based on the code of the `PerformanceCritical` checker. In the next diff, I will refine the list of acceptable allocations, like new exceptions, etc, and add the list of corresponding tests.
