Here's v2 of the slab-fix patch.

I've included the sentinel check fix.  This passes make check-world
for me when do a 32-bit build on my x86_64 machine and adjust
pg_config.h to set MAXIMUM_ALIGNOF to 8.

Any chance you could run make check-world on your 32-bit Raspberry PI?

I'm also wondering if this should also be backpatched back to v10,
providing the build farm likes it well enough on master.
