This attempts to be a higher-level description of our inlining heuristics
and decision trees than the source, where the work is spread out between
ExprEngine (mostly in ExprEngineCallAndReturn.cpp) and CallEvent, with a
few other classes participating as well.

function arguments and arguments for variadic functions are of a particular
type which is determined by some other argument to the same function call.
Usecases include:
* MPI library implementations, where these attributes enable checking that
buffer type matches the passed MPI_Datatype;
* for HDF5 library there is a similar usecase as MPI;
* checking types of variadic functions' arguments for functions like
fcntl() and ioctl().

These require special handling, which we don't currently handle. This is being
put in place to ensure we don't do invalid symbol table lookups or try to parse
invalid assembly. The test cases just makes sure the latter isn't happening.

ArrayRef<SourceRange> for ranges. This
removes conceptual clutter, and can allow us to easy migrate to C++11 style for-range loops if we
ever move to using C++11 in Clang.

same time.
This fixes several issues:
- removes egregious hack where PlistDiagnosticConsumer would forward to HTMLDiagnosticConsumer,
but diagnostics wouldn't be generated consistently in the same way if PlistDiagnosticConsumer
was used by itself.
- emitting diagnostics to the terminal (using clang's diagnostic machinery) is no longer a special
case, just another PathDiagnosticConsumer. This also magically resolved some duplicate warnings,
as we now use PathDiagnosticConsumer's diagnostic pruning, which has scope for the entire translation
unit, not just the scope of a BugReporter (which is limited to a particular ExprEngine).
As an interesting side-effect, diagnostics emitted to the terminal also have their trailing "." stripped,
just like with diagnostics emitted to plists and HTML. This required some tests to be updated, but now
the tests have higher fidelity with what users will see.
There are some inefficiencies in this patch. We currently generate the report graph (from the ExplodedGraph)
once per PathDiagnosticConsumer, which is a bit wasteful, but that could be pulled up higher in the
logic stack. There is some intended duplication, however, as we now generate different PathDiagnostics (for the same issue)
for different PathDiagnosticConsumers. This is necessary to produce the diagnostics that a particular
consumer expects.

The latter is either an input or an output. Unfortunately, it's difficult to

and remove ASTContext reference (which was frequently bound to a dereferenced
null pointer) from the recursive lump of printPretty functions. In so doing,
fix (at least) one case where we intended to use the 'dump' mode, but that
failed because a null ASTContext reference had been passed in.

This is analogous to our handling of pointer dereferences: if we
dereference a pointer that may or may not be null, we assume it's non-null
from then on.
While some implementations of C++ (including ours) allow you to call a
non-virtual method through a null pointer of object type, it is technically
disallowed by the C++ standard, and should not prune out any real paths in
practice.
[class.mfct.non-static]p1: A non-static member function may be called
for an object of its class type, or for an object of a class derived
from its class type...
(a null pointer value does not refer to an object)
We can also make the same assumption about function pointers.

This is the other half of C++11 [class.cdtor]p4 (the destructor side
was added in r161915). This also fixes an issue with post-call checks
where the 'this' value was already being cleaned out of the state, thus
being omitted from a reconstructed CXXConstructorCall.
