refactoring r63073.
* cont.c (root_fiber_alloc): call `ConvertThreadToFiber()` here. `rb_fiber_t` for root_fiber is allocated before running Threads. Fiber objects wrapping this rb_fiber_t for root_fiber are created when root Fiber object is required explicitly (for example, Fiber switching and so on). We can put calling `ConvertThreadToFiber()`. In other words, we can pending `ConvertThreadToFiber()` until Fiber objects are created. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63090 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
