Tom de Vries b243ba58e8 [gdb/testsuite] Stabilize execution order in omp-par-scope.c 
In openmp test-case gdb.threads/omp-par-scope.exp we xfail and kfail dependent
on omp_get_thread_num ().  Since execution order of the threads can vary from
execution to execution, this can cause changes in test results.

F.i., we can see this difference between two test runs:
...
-KFAIL: single_scope: first thread: print i3 (PRMS: gdb/22214)
+PASS: single_scope: first thread: print i3
-PASS: single_scope: second thread: print i3
+KFAIL: single_scope: second thread: print i3 (PRMS: gdb/22214)
...
In both cases, the KFAIL is for omp_get_thread_num () == 1, but in one case
that corresponds to the first thread executing that bit of code, and in the
other case to the second thread.

Get rid of this difference by stabilizing execution order.

Tested on x86_64-linux.

gdb/testsuite/ChangeLog:

2020-07-20  Tom de Vries  <tdevries@suse.de>

	* gdb.threads/omp-par-scope.c (lock, lock2): New variable.
	(omp_set_lock_in_order): New function.
	(single_scope, multi_scope, nested_func, nested_parallel): Use
	omp_set_lock_in_order and omp_unset_lock.
	(main): Init and destroy lock and lock2.
