[RFC] switch-threads.exp added tests.

I added couple of tests to explicitly test switching threads. Any
comments/suggestion?

The numbers of threads depend on the operating system, and on the order
in which GDB notices new threads.  For instance the LinuxThreads
manager thread, or a remote target which does not report new threads
immediately.

Also the format of "info threads" output is target specific.  LWP comes
from the Linux specific native code.
