 If you start looking for queries to optimize on any random WordPress site,
 you'll find queries like this:

 {{{
 SELECT option_value FROM bphtc_options WHERE option_name = 'WPLANG' LIMIT
 1
 }}}

 where this happens for WPLANG, but also for lots of other options. This
 only happens when the option doesn't exist, because core already does this
 query before all of them:

 {{{
 SELECT option_name, option_value FROM bphtc_options WHERE autoload = 'yes'
 }}}

 Because it does that, we can prevent queries like the former to happen
 entirely if we know that it *should* be auto loaded. To be able to do that
 we should add a third parameter to `get_option()` that allows us to say
 "don't fallback to a database query if this option wasn't auto loaded".
