infrun: extract out a code piece into 'mark_non_executing_threads' function
This is a refactoring. The extracted function is placed deliberately
before 'stop_all_threads' because the function will be re-used there
in a subsequent patch for handling an exit status kind received from
a thread that GDB attempted to stop.

* infrun.c (handle_inferior_event): Extract out a piece of code
into...
(mark_non_executing_threads): ...this new function.
