[PATCH 1/3] New test case for PR12929.
PR12929 was fixed by this patch,
Flip the interpreter to synchronously wait for commands finishing, in command lists and similars
http://sourceware.org/ml/gdb-patches/2011-09/msg00037.html
but we don't have a test case for it. My following patch will affect this
part, so I add a test case to make sure my patch doesn't break anything.
gdb/testsuite:
* gdb.python/py-sync-interp.c: New.
* gdb.python/py-sync-interp.exp: New.
