[CRYPTO]: Add cipher speed tests

Browse Source 
From: Reyk Floeter <reyk@vantronix.net>

I recently had the requirement to do some benchmarking on cryptoapi, and
I found reyk's very useful performance test patch [1].

However, I could not find any discussion on why that extension (or
something providing a similar feature but different implementation) was
not merged into mainline.  If there was such a discussion, can someone
please point me to the archive[s]?

I've now merged the old patch into 2.6.12-rc1, the result can be found
attached to this email.
