Change Sema to avoid these asserts.

implemented a (codegen) target hook for __builtin_extend_pointer.
I'm also making it return a uint64_t instead of an unsigned word;  this
comports with typical usage (i.e. the one use I know of).

I don't know if any of the existing targets requires this hook to be
set (other than x86 and x86_64, which I know do not).

does, document the results and then implement __builtin_extend_pointer for
platforms where it's a no-op.

category.  Use this in a few places to eliminate unnecessary TST cases and
do some future-proofing.  Provide terrible manglings for typeof.  Mangle
decltype with some hope of accuracy.

Our manglings for some of the cases covered in the testcase are different
from gcc's, which I've raised as an issue with the ABI list.

When laying out vtables for virtual bases in construction vtables, we need to check if the vtable is a primary base in the layout class.

llvm-svn: 97361

Pass information about whether a base is virtual or not down to getCtorVtable, we need this information in the vtable builder.

Fix to dumpLayout; we want to be able to dump address points even if the vtable doesn't have any methods.

Enable the new vtable layout code for vtables that aren't construction vtables. (This doesn't mean that we emit LLVM IR using it yet, it just means that it's running and hopefully not crashing or asserting).

Stub out more of the 'this' pointer adjustment fixes I've been planning. Start using a set vector for primary bases so they will be ordered.

Fix another vtable layout bug; we weren't looking hard enough for overriden functions when determining if an overrider will ever be used.

Fux a bug where we were trying to add overriders for non-virtual bases of virtual bases more than once.

so get the name from Var rather than the original decl.

Get rid of 'this' adjustments from the FinalOverriders class since they can be different for the same overrider in different parts of the vtable.
