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.

David Blaikie bbafb8a745 Unify naming of LangOptions variable/get function across the Clang stack (Lex to AST). 
The member variable is always "LangOpts" and the member function is always "getLangOpts".

John McCall f937c023bf Rename TagDecl::isDefinition -> isCompleteDefinition 
for better self-documenting code, since the semantics
are subtly different from getDefinition().
