I confirm comment #2. We do have incoming args being saved in callee-saved
regs and those callee-saved regs then being used.
However, there are additional problems to solve before this function will ever
be shrink-wrapped. We have uses of callee-saved regs for more than just
incoming args. For instance, "mask" gets put in r24 and "ep0" in r25 in the
first bb, and a little later, "i" in r29 and others are used for other
intermediate values.
