Paul Mackerras b122577a4e FPU: Be more careful about preserving low-order bits in multiply-add instrs 
Add code to check whether bits of S which don't get shifted into R are
non-zero, and set X if they are, so that rounding in multiply-add
instructions works correctly.  This needs to be done after normalization
in the case of very small results, where potentially all the non-zero
bits in S do get shifted into R.

Also fix an incorrect test case, and add another multiply-add test case.
