simplehash: Allow for use in frontend code.
Commit
48995040d5e7b1e9bac35d72aff326cae002219d removed the largest
barrier to use of simplehash in frontend code, but there's one more
problem: it uses elog(ERROR, ...) or elog(LOG, ...) in a couple of
places. Work around that by changing those to pg_log_error() and
pg_log_info() when FRONTEND is defined.
Patch by me, reviewed by Andres Freund.
