We would previously skip any function that had one of these.
A no-op translation is sufficient to fix this issue (see new E2E test).

`infer capture -a checkers ...` would accidentally trigger the analysis phase.
This crashes the Buck flavors integration when used with `--reactive` because
.start never gets created in the infer-out-* subfolders of buck-out.

Target patterns/aliases rarely contain only targets supporting infer flavor, so it makes sense to automatically filter kinds with handle in those cases.

To resole #797 this adds runtime option to select VFS for SQLite,
When infer runs on WSL this defaults to "unix-excl" (https://sqlite.org/vfs.html) and if VFS is specified, then WAL is not enabled (since WAL is non compatible with custom VFS - https://www.sqlite.org/wal.html).

Summary:
We need to use the procedure description of the callees for lazy dynamic dispatch and for the resolution of the lambda. We may also need this information in other analyses, e.g. for RacerD. This diff makes the procedure description of the callees as part of the summary.
The procedure description has been part of the summary for a while already without noticeable decrease in performance.

Summary:
This diff adds a new way of executing blocks when they are passed as parameters to a method. So far we just skipped the block in this case.
Now we can execute it. Let's demonstrate with an example. Say we have
//foo has a block parameter that it executes in its body
foo (Block block) { block();}
// bar calls foo with a concrete block
bar() {
foo (^(){
self->x = 10;
});
};
Now, when we call the method foo with a concrete block, we create a copy of foo instantiated with the concrete block, which in itself is translated as a method with a made-up name.
The copy of foo will get a name that is foo extended with the name of the block parameter, the call to the block parameter will be replaced to a call to the concrete block, and the captured variables
of the concrete block (self in this case), will be added to the formals of the specialized method foo_block_name.
This is turned on at the moment for ObjC methods with ObjC blocks as parameters, and called with concrete blocks. Later on we can extend it to other types of methods, and to C++ lambdas, that are handled similarly to blocks.
Another extension is to check when the block has been called with nil instead of an actual block, and raise an error in that case.
After this diff, we can also model various methods and functions from the standard library that take blocks as parameters, and remove frontend hacks to deal with that.

Summary:
This confuses the SIOF checker and causes false positives. This dummy deref is
generated for constructors of classes that are modeled as being pointer types
instead of the actual class in infer, typically for smart pointers. I do not
understand how this works.
The biabduction also analyses this code, so might now get confused itself.
