i386: specialize `copyinmsg' and `copyoutmsg'
Previously, `copyinmsg' was the same function as `copyin'. The former
is for messages, and the size of messages is a multiple of four.
Likewise for `copyoutmsg'.
Provide a specialized version of both functions. This shaves off a
couple of instructions and improves our IPC performance.
* i386/i386/locore.S (copyinmsg): New function.
(copyoutmsg): New function.
