  Changed paths:
    M libcxx/include/future
    A libcxx/test/std/thread/futures/futures.async/thread_create_failure.pass.cpp
    A libcxx/test/std/thread/futures/futures.async/wait_on_destruct.pass.cpp

  Log Message:
  -----------
  [libc++] Don't try to wait on a thread that hasn't started in std::async, take 2 (#130145)

If the creation of a thread fails, this causes an idle loop that will
never end because the thread wasn't started in the first place.

This also adds a test for the regression reported in #125433 to make
sure we're not reintroducing it later.

Fixes #125428
