simplehash: Allow for use in frontend code.

Browse Source 
Commit 48995040d5 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.
