riscv also got an -munroll-only-small-loops option. This means that
the doc urls for the existing -munroll-only-small-loops for i386 got
renamed (so they have distinct names). riscv.opt.urls already got
regenerated. Now also regenerate i386.opt.urls
Fixes: d15703b27aa4 RISC-V: Add small loop unrolling support via -munroll-only-small-loops
gcc/ChangeLog:
* config/i386/i386.opt.urls: Regenerate.
