Check for finite/infinity parms in IBM Long Double 128 fmal( )
...
This patch addresses some IBM Long Double 128 fmal () test-ldouble.out
and test-ildoubl.out failures. If the ‘x’ and ‘y’ parameters are
finite values and ‘z’ is infinity, the result of fmal () should be ‘z’
not NaN.

integer and handle the words separately. We have wide registers.
This patch implements a 64-bit ceil version. Ideally all other
functions will be converted over time.
