_helpers.firstword(): a new function to extract the first 32 bits.

This is a pretty common operation in git.py and it speeds up cmd/memtest
results considerably: from 3.7 seconds to 3.0 seconds.

That gets us *almost* as fast as we were before the whole statistical
guessing thing, but we still enjoy the improved memory usage.
