I got three PRs about optional reloads patch which I committed to the
trunk on Friday.
Sorry, I can not work on these PRs this week. So I decided to switch
optional reloads off temporarily. I'll return to the PRs next week.
The patch was successfully bootstrapped on x86-64.
Committed as rev. 200899.
