don't explode if the offset we get is zero.  This can happen if
you have an empty virtual base class.

While I'm at it, remove an unnecessary block from the IR-generation
of the null-check, mark the eventual GEP as inbounds, and generally
prettify.

The only caveat is renumbering CXCommentKind enum for aesthetic reasons -- this
breaks libclang binary compatibility, but should not be a problem since API is
so new.

This also fixes PR13372 as a side-effect.

This also tidies up a couple of other tools we were (partially) installing:
* c-index-test was being installed but shouldn't be (it's just a clang-dev tool)
* diagtool was being installed in cmake but not make (& shouldn't be installed in either)

For now this will stay on, but this way it's easy to switch off if we need
to pull back our support for a while.

While usually we'd use a symbolic region rather than a straight-up Unknown,
we can still generate unknowns via array subscripts with symbolic indexes.
(And if this ever changes in the future, we still shouldn't crash.)

Warn about using pointers to const-qualified types as arguments to
scanf. Ignore the volatile qualifier when checking if types match.

This was causing a crash in our array-to-pointer logic, since the region
was clearly not an array.

attribute. It is a variation of the x86_64 ABI:

* A struct returned indirectly uses the first register argument to pass the
  pointer.
* Floats, Doubles and structs containing only one of them are not passed in
  registers.
* Other structs are split into registers if they fit on the remaining ones.
  Otherwise they are passed in memory.
* When a struct doesn't fit it still consumes the registers.

type and then propagated to the function. This was failing for destructors,
constructors and constructors templates since they don't have a return type.

Fix that by directly calling processTypeAttrs on the dummy type we use as the
return type in these cases.

This removes explicit checks for 'this' and 'self' from
Store::enterStackFrame. It also removes getCXXThisRegion() as a virtual
method on all CallEvents; it's now only implemented in the parts of the
hierarchy where it is relevant. Finally, it removes the option to ask
for the ParmVarDecls attached to the definition of an inlined function,
saving a recomputation of the result of getRuntimeDefinition().

The inlinable portion of the test relies on attributes/instead of the
function implementation.

sure to update the exception specification on the declaration as well as the

Previously, we were only checking the origin expressions of inlined calls.
Checkers using the generic postCall and older postObjCMessage callbacks were
ignored. Now that we have CallEventManager, it is much easier to create
a CallEvent generically when exiting an inlined function, which we can then
use for post-call checks.

No test case because we don't (yet) have any checkers that depend on this
behavior (which is why it hadn't been fixed before now).

accurate by asking the parser whether there was an ambiguity rather than trying
to reverse-engineer it from the DeclSpec. Make the with-parameters case have
better diagnostics by using semantic information to drive the warning,
improving the diagnostics and adding a fixit.

Patch by Nikola Smiljanic. Some minor changes by me to suppress diagnostics for
declarations of the form 'T (*x)(...)', which seem to have a very high false
positive rate, and to reduce indentation in 'warnAboutAmbiguousFunction'.

type of generated call to super dealloc is 'void'
and asserts if user's dealloc is not of 'void type.
This rule must be enforced in clang front-end (with a 
fixit) if this is not the case, instead of asserting in CodeGen.
