Fix use of non-existent DIAGNOSTIC_IGNORE_UNUSED_FUNCTION

A previous commit removed DIAGNOSTIC_IGNORE_UNUSED_FUNCTION because it is
known not to work correctly for some older versions of GCC.

gdb/ChangeLog:

2019-12-12  Luis Machado  <luis.machado@linaro.org>

	* gdbsupport/thread-pool.c (set_thread_name): Add ATTRIBUTE_UNUSED
	to both functions.
	Remove use of DIAGNOSTIC PUSH/POP and DIAGNOSTIC_IGNORE_UNUSED_FUNCTION.
