Convert Clang over to resuming from landing pads with llvm.eh.resume.
...
It's quite likely that this will explode, but I need to know how. :)

Implement a new, much improved version of the cleanup hack. We just need
...
to be careful to emit landing pads that are always prepared to handle a
cleanup path. This is correct mostly because of the fix to the LLVM
inliner, r132200.

The array-size operand to a new-expression is not necessarily a size_t.
...
It can be larger, it can be smaller, it can be signed, whatever. Handle
all the crazy cases with grace and spirit.

check is triggered appropriately. Reported on cfe-dev.

Itanium guards and use a slightly different compiled-in API.

It's not safe to use the generic CXXMethodDecl overload of CGT::getFunctionInfo
...
to set up a destructor call, because ABIs can tweak these conventions.

Abstract IR generation of array cookies into the C++ ABI class and
...
implement ARM array cookies. Also fix a few unfortunate bugs:
- throwing dtors in deletes prevented the allocation from being deleted
- adding the cookie to the new[] size was not being considered for
overflow (and, more seriously, was screwing up the earlier checks)
- deleting an array via a pointer to array of class type was not
causing any destructors to be run and was passing the unadjusted
pointer to the deallocator
- lots of address-space problems, in case anyone wants to support
free store in a variant address space :)
