LP#1588543: further speed up record attribute ingest

Following a suggestion from Dan Wells, this patch adds
an index on config.coded_value_map(ctype). My testing shows
that the index by itself can halve the time required to
fully ingest a new record; in conjunction with the
change in the previous patch, full reingest time is
reduced by about 60%.
