Fix powerpc32 ceil, rint etc. on sNaN input (bug 20160).
The powerpc32 versions of ceil, floor, round, trunc, rint, nearbyint
and their float versions return sNaN for sNaN input when they should
return qNaN.  This patch fixes them to add a NaN argument to itself to
quiet sNaNs before returning.  The powerpc64 versions, which have the
same bug, will be addressed separately.

Tested for powerpc32.

	argument to itself before returning the result.
