I noticed that the Altivec / VMX register names are missing too, so
they should be added.  Ian on #gcc said we might want to #ifdef the
names which we can do for Altivec / VMX with #ifdef __ALTIVEC__.
However, the __VSX__ macro won't exist until the VSX support is added
sometime in the future.

Ian, do you want me to add the VSX names to gcc/config/rs6000/ppc-asm.h
#ifdef'd with __VSX__ now, even though __VSX__ won't exist for a while,
or just wait until we submit the rest of the VSX code?

Yes, that was an oversite on my part, sorry.  Here's the patch to add
the names to pre_defined_registers.

This has passed bootstrap and make check.  Ok for mainline?

	* config/tc-ppc.c (pre_defined_registers): Add "f32" to "f63",
	"f.32" to "f.63", "vs0" to "vs63" and "vs.0" to "vs.63".
