The attached adds a test to tuplesort to exercise BumpAllocLarge()

I don't see a way to exercise those. They're meant to be "can't
happen" ERRORs.  I could delete them and use BogusFree, BogusRealloc,
BogusGetChunkContext, BogusGetChunkSpace instead, but the ERROR
message would be misleading. I think it's best just to leave this.
