Fix minor issues with new unicode {de,re}composition code

The table generation script would incorrectly complain in the recomposition sorting when matching code points. This would not have caused the generation of an incorrect table. Note that this condition is not reachable yet, but could have been reached with future updates. pg_bswap.h does not need to be included in the frontend.x Author: John Naylor Discussion: https://postgr.es/m/CAFBsxsGWmExpvv=61vtDKCs7+kBbhkwBDL2Ph9CacziFKnV_yw@mail.gmail.com
