regcache::cooked_read unit test
This patch adds a unit test to regcache::cooked_read. This unit test is a
little different from normal unit test, it is more about conformance test
or interaction test. This test pass both raw register number and pseudo
register number to regcache::cooked_read, in order to inspect 1) return
value of cooked_read, 2) how are target_ops to_xfer_partial,
to_{fetch,store}_registers called (because regcache is updated by means of
these three target_ops methods). With this test here, we have a clear
picture about how each port of GDB get cooked registers.
This patch also shares some code on mock target.
