Do we ever use the "register" keyword anymore? I don't make "suggestions" to
gcc, I hit it with a clue-by-by four.

I'd be happy to just figure out what the policy is. It seems like
the "inline" keyword should no longer be used, and either say __always_inline
or leave it to the compiler. If there's a good counter-argument, I'd love to
hear it.
