Simplify/speed up assertion cross-check in ginCompressPostingList().
I noticed while testing some other stuff that the CHECK_ENCODING_ROUNDTRIP logic in ginCompressPostingList could account for over 50% of the runtime of an INSERT with a GIN index. While that's not relevant to production performance, it's still kind of annoying in a debug build. Replacing the loop around short memcmp's with one long memcmp works just as well and is significantly faster, at least on my machine.
