Heikki Linnakangas 24c88cd39d Fix pg_trgm's picksplit function with all-true datums ...

The CACHESIGN.sign field is a BITVECP, not a TRGM, so you should not
use GETSIGN() on it. You don't get a compiler warning because the
GETSIGN() macro includes a cast. It resulted in a bogus read beyond
end of buffer, which would cause bad split decisions or a crash if
you're very unlucky.
