Major changes to use Intel's optimized SHA512 code for SHA512 and SHA512/256.

Browse source 
Remove earlier SHA256 code which is slower than SHA512/256 (on 64-bit CPU).
Use HMAC from Alan Saddi's implementation for cleaner, faster code.

; The two new schedule QWORDS are stored at [W_t(%%t)] and [W_t(%%t+1)].

; stitched to take advantage of instruction-level parallelism.

; by one tab. Vectored instructions (for the message scheduler) are indented
