Timur Iskhodzhanov 05e3670498 Recommit r183298+r183300 'Get rid of VTableContext::ComputeMethodVTableIndices() and VTableContext::getNumVirtualFunctionPointers()'
In r183298, I've used llvm::SmallPtrSet<..., 8> instead of llvm::SmallVector<..., 8> for NewVirtualFunctionsTy by mistake.
This only manifested when a class had more than 8 virtual functions, which wasn't covered by unit-tests

David Blaikie 40ed29730b Revert Decl's iterators back to pointer value_type rather than reference value_type
In addition, I've made the pointer and reference typedef 'void' rather than T*
just so they can't get misused. I would've omitted them entirely but
std::distance likes them to be there even if it doesn't use them.

This rolls back r155808 and r155869.

David Blaikie 2d7c57ec1d Remove the ref/value inconsistency in filter_decl_iterator.
filter_decl_iterator had a weird mismatch where both op* and op-> returned T*
making it difficult to generalize this filtering behavior into a reusable
library of any kind.

This change errs on the side of value, making op-> return T* and op* return
T&.

John McCall b6c4a7ef21 For the annals of subtle but terrible bugs: fix a longstanding bug
in vtable layout where virtual methods inherited from virtual bases
could be assigned the same vcall adjustment slot if they shared
a name and parameter signature but differed in their
cv-qualification.  The code was already trying to handle this
case, but unfortunately used the ordinary type qualifiers
(which are always empty here) instead of the method qualifiers.
This seems like something that the API should discourage, but
I don't know how to carry that principle out in this instance.

Eliminate this function's need for an ASTContext while we're at it.

This bug affects the ABI, and fixing it brings us into accord with
the Itanium ABI (and GCC's implementation of it), but, obviously,
technically breaks full compatibility with previous releases of Clang.
Just letting you know.
