I'm separately committing this because it incidentally changes some
block orderings and minor IR issues, like using a phi instead of
an unnecessary alloca.

replace all uses of the entry with the predecessor. There are no cleanups
relying on this right now, but if we ever want a cleanup with a phi inside
it, this will be important.

class to be passed around. The line between argument and return types and
everything else is kindof vague, but I think it's justifiable.

for the same destination, then we must potentially rewrite the initial branch
of every fixup. Without this patch, a short-circuit check meant to prevent
a switch case from being redundantly added was preventing later fixups from
being processed. Fixes PR8175 (again).

the cleanup might not be dominated by the allocation code.
In this case, we have to store aside all the delete arguments
in case we need them later. There's room for optimization here
in cases where we end up not actually needing the cleanup in
different branches (or being able to pop it after the
initialization code).
Also make sure we only call this operator delete along the path
where we actually allocated something.
Fixes rdar://problem/8439196.

Make CGT defer to the ABI on all member pointer types.
This requires giving CGT a handle to the ABI.
It's way easier to make that work if we avoid lazily creating the ABI.
Make it so.

pointers. I find the resulting code to be substantially cleaner, and it
makes it very easy to use the same APIs for data member pointers (which I have
conscientiously avoided here), and it avoids a plethora of potential
inefficiencies due to excessive memory copying, but we'll have to see if it
actually works.
