Summary: @public remove `is_instance` function parameter that was used for
blocks only. Instead, pass context everywhere - it holds information that is
very relevant when defining block.

1. Add support for `this` keyword. It will allow to access fields/methods of the object from the method body.
2. Fix problem with method formals to add pointer to type of first parameter (which corresponds to `this`)

Get newest goodness from facebook-clang-plugins
that allows us to change type of type_ptr during deserialization
We are modifying clang_ast_types.ml that fcp/clang-ocaml expects to
exist - we provide our own implementations of:
t_ptr, pointer_to_type_ptr, type_ptr_to_pointer

First diff to give better language information in the frontend.
This information is necessary to understand when 'self' is objc keyword,
when 'this' is C++ keyword and when they are not.

There was an inconsistency with the type of `stats.json` created by `inferlib.py` and InferAnalyze. This diff cleans up the thing and uses two different files to saves the statistics to clarify what gets created by the analysis, i.e. `proc_stats.json` and what gets created all the time `stats.json`.

qual_type was the same as type_ptr, so it was removed.
This commit makes it compatible with facebook-clang-plugins
Commands ran:
codemod --extensions ml,mli 'qual_type' 'type_ptr'
codemod --extensions ml,mli 'qt' 'tp'
If there is any other popular name for qual_type, let me know

Summary: @public Infer previously did not work correctly when a function returns the result of a skip function:
```
retUndef() {
x = undefined();
return x;
}
derefUndef() {
y = retUndef();
y.doSomething(); // Symexec_memory_error here, prevents spec inference
}
```
The problem is that angelic mode did not know to add the return value of `retUndef()` to the footprint.
This diff fixes the problem by adding return values marked with the `Aundef` attribute to the footprint.
This is done lazily (e.g., a value only gets added to the footprint when you try to deref it).

We no longer rely on existence of qt_raw field.
Update facebook-clang-plugins so that this field
is not even exported. This should give us some perf wins
since qual_type is written in a lot of places

Summary:
Using the qualified names of fields to create mangled names.
This removes the need to search for the fields in the tenv when translating a field access.
That was only done to build the correct mangled name,
The rest of the changes are using the qualified names for ivars and property names in the property module,
which is needed to make it work. Basically a big chain of changes of using qualified names to make the code
compile.
Summary:
This diff aims at removing the occurrences of the types in string form so that we can remove them
from the ast which will save space.
There is one occurrence left regarding attributes that will be handled later by Andrzej.
We build a function to create a string out of a function type used for name mangling.
Summary:
frontend and backend assume that Sil.Struct
doesn't have methods nor inheritance. In order to plug C++
classes we probably need them to be Sil.Class
Summary:
See D2465673, replacing `-gmodule` with equivalent flags, as per http://reviews.llvm.org/D11958
The `-fmodule-format` is not available on Xcode's clang, so skip it for now.
Summary:
In the new clang the parameters to these functions have notnull annotations, because of that infer tests fail. More concretely, the tests say there would be a memory leak. In the symbolic execution of those functions though, an inconsistency is created, because the parameter was nil, and the constraint argument should not be nil was also there, which leads to an error in the execution and no object is created, hence, no memory leak.
Summary:
C function names depend only on their name (and their file is they are static, and their type if we are in C++)
This is more in sync with the actual semantics of C function names than the previous implementation.
Summary:
`get_resource_or_undef` attribute is weird and was causing problems for me in another diff.
This diff refactors the attribute categories to make resource and undef separate.
Summary:
Harness generation was using the autogenerated harness file as the source file,
but placing the harness code in the cfg belonging do a different source file. Fix this confusion
by using the source file of the cfg containing the harness code throughout.
Summary:
The python parser for '-d <dir>' interpreted '-deprecation'
as '-d eprecation', which is not desirable. Fixed it by teaching the parser to
parse '-deprecation' as a boolean flag.
Summary:
Some build systems compile files both under the project root and under temporary
directories (e.g., /tmp), so there need not be a single project root. Just use absolute paths
in the case that we can't resolve a relative path from the project root.
Summary:
Added two annotations @TrueOnNull and @FalseOnNull to be used for boolean functions to specify what value is returned when the argument is null.
Added model for TextUtils.isEmpty, which corresponds to the annotation
@TrueOnNull
static boolean isEmpty(@Nullable java.lang.CharSequence s)
Summary:
Make infer run with clang 3.7.0. Small changes are due to differences
in output of clang
NOTE: this diff will require recompiling clang (it takes time)
