Description was changed from

==========
Remove calls to deprecated MessageLoop methods from tools/.

This Cl removes most calls to these methods from tools/ for files that
compile on Windows or Linux:
- MessageLoop::PostTask
- MessageLoop::PostDelayedTask
- MessageLoop::ReleaseSoon
- MessageLoop::DeleteSoon
- MessageLoop::Run
- MessageLoop::RunUntilIdle

Also note that calls to thread->message_loop()->task_runner() have
been replaced with thread->task_runner() (|thread| is a base::Thread).

This CL was generated by running the clang-tidy checks available here
https://crbug.com/616447#c153 on Windows and Mac and by applying a few
manual fixes.
