0.9.9.32:
	Fix hideously embarrassing ppc assembly bug in reg_LRA
	computation.
	... no longer go wrong if bit 15 of lra is set.

	(The symptoms from this have been reported many, many times:
	segmentation faults in the first triggered GC.  Kevin Rosenberg
	reported it first from my trawl on sbcl-devel, but I think it's
	been known for longer than that.  Previously it had been
	dismissed as gcc miscompilation problems, because the problem
	disappeared when using a different version of gcc, for any
	individual developer: in retrospect, the fact that it was our
	bug after all is pretty obvious from the fact that we were never
	able to characterize particular versions of gcc which were bad.)
