[CRYPTO] sha1: Avoid shifting count left and right
This patch avoids shifting the count left and right needlessly for each call to sha1_update(). It instead can be done only once at the end in sha1_final(). Keeping the previous test example (sha1_update() successively called with len=64), a 1.3% performance increase can be observed on i386, or 0.2% on ARM. The generated code is also smaller on ARM.
