Log message:
    This patch fixes a regression caused by my recent changes to heap
    tuple header.  The fix is based on the thought that HEAP_MOVED_IN is
    not needed any more as soon as HEAP_XMIN_COMMITTED has been set.  So
    in tqual.c and vacuum.c the HEAP_MOVED bits are cleared when
    HEAP_XMIN_COMMITTED is set.

    Vacuum robustness is enhanced by rearranging ifs, so that we have a
    chance to elog(ERROR, ...) before an assertion fails.

    A new regression test is included.
