[Bug optimization/14042] C++ abstraction penalty is high in simple cases

This still doesn't produce the same code as the C version.  I now get:

L11:
	vaddfp v0,v11,v13
	addi r2,r2,1
	vaddfp v1,v10,v12
	cmplw cr7,r2,r5
	vmaddfp v8,v0,v11,v13
	vmaddfp v6,v1,v10,v12
	vsubfp v9,v0,v13
	vsubfp v7,v1,v12
	vor v11,v8,v8
	vor v10,v6,v6
	vor v13,v9,v9
	vor v12,v7,v7
	blt+ cr7,L11


note the extra useless copies at the end of the loop.

If you'd like me to enter a new bug on this (since the title is now incorrect, I guess), just let me know.
