  This changes windows_thread_info::name to be a unique_xmalloc_ptr,
removing some manual memory management.

2019-10-14  Tom Tromey  <tromey@adacore.com>

	* windows-nat.c (handle_exception)
	(windows_nat_target::thread_name): Update.
	* nat/windows-nat.h (windows_thread_info): Remove destructor.
	<name>: Now unique_xmalloc_ptr.
