Add tests for loop_break and loop_continue commands

I grepped the testsuite for loop_break and loop_continue and didn't find
anything, so I wrote some simple tests for those.

gdb/testsuite/ChangeLog:

	* gdb.base/commands.exp: Call the new procedures.
	(loop_break_test, loop_continue_test): New procedures.
