From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>
rol (rotate a 32-bit value left) is called a lot of times for each
sha1 calculation, and it becomes a bottleneck when inline expansion is
turned off (with debug build) and tracer is enabled. It's not so
important to profile the function, so let's inline it forcely.
