Sorry for the long time reviewing this set of patches.  I've just
tweaked it to bring it up to the current code base and committed it.
It's largely unchanged from your submission apart from:

1) Updates to incorporate latest changes made by Richard Sandiford.
2) Minor tweak to simplyfy the iWMMXT builtins initialization.

R.
