Regarding gcc.c-torture/execute/920501-8.c, there's an extra "0" in the
"1.000000" part. Comparing to results for other targets (mmix, frv), it seems
the core sprintf function is miscompiled!

Upon closer examination, the miscompiled vfprintf.c is missing a compare insn.
This seems to have been the same bug as PR 19898.

One final note: this code is at the point in the simulator trace where the
number of digits is calculated and first seen to be different between the faulty
code and working code (that is, working due to unrelated rearrangement).
