This patch adds some RTL-SSA helper functions. They will be

The patch contains the first non-template out-of-line function declared
in movement.h, so it adds a movement.cc. I realise it seems a bit
over-the-top to have a file with just one function, but it might grow
in future. :)

I assumed that you'll end up with more code in there, so I'm certainly
OK with having just one function in the file right now.
OK for the trunk.
